Get yourself a pH reader - this is the one I use. Otherwise, you need to stick to approved recipes.

Edit: Time to transplant, they look big enough and the solo cups have shallow soil to begin with.

Edit2: looks like you have more perlite than soil, I would do a light n feeding after transplant.

I wouldn't use the strips they are shit. Get a liquid ph tester kit at the very least, I use this ph meter it works like a charm don't waste money on a cheap ph meter either. You will regret it.

u/GrowInTheDark · 3 pointsr/microgrowery

Get the Apera. DON'T GET THE BLUELAB.

> if you dont mind having to calibrate your ph pen every time you use it just get a cheap 10 dollar ph pen. I dont mean to imply that all of them need to be calibrated every single time but i am saying don't expect them to work perfectly.. i advise you just assume that you will need to be calibrating it very very often if you use it very very often so you dont set yourself up for disappointment.
>
> but If you want a solid ph pen get an apera ph pen (i have this one)
>
> I had a yellow ph pen that lasted me a couple months before it went to crap. then i went through two broken Bluelab ph Pens (they werent mine though they were used and handed down from a close friend). I always read about bluelab being the ph pen every one should have. that is bullshit imo. If you do your research you will see lots of stories with bluelabs going to crap, probably because they dried out... but stilll.... its very commmon...
>
> i HIGHLY recommend apera ph Pens. I got the 50 dollar version and it works perfectly just like a bluelab (in working condition) does. It has a one button auto calibration... and it can calibrate using three points if you want.. and its dead on accurate and reminds you when to calibrate and it tells you when the ph reading is stable.. and tells you the temperature of the solution.. Its nice for 50 dollars. Or you can dish out more and get the version that has a repplaceable probe. Keep in mind the replaceable probe is about 40 bucks so i ended up getting the 50-dollar pen thinking that if it ever goes to crap i might as well buy a nother one instead of just replacing the probe...

u/Streiche93 · 3 pointsr/microgrowery

I have tried a few of the $15-$25 pens on amazon, they all seem very similar and very inaccurate. Eventually I got tired of it and opted to spend a bit more ($50ish) and picked up this meter:

And have been extremely pleased with its performance. Quick and accurate readings for both pH and water temperature.

u/is_this_available07 · 3 pointsr/SpaceBuckets

I have an Apera pen and it works really well. I like it for sure.
I used to use the drops suck, and they suck. It's hard to get an accurate reading. The pen is great for accurate readings, but it takes up to 20 seconds to fix on the correct pH, which at times feels like forever.

This is the one I have: https://www.amazon.com/Apera-Instruments-AI209-Waterproof-Accuracy/dp/B01ENFOHN8/ref=sr_1_2?ie=UTF8&qid=1499548253&sr=8-2&keywords=ph+pen

Meh... Def not worth the trouble imo.

This one is awesome. https://www.amazon.com/dp/B01ENFOHN8/ref=cm_sw_r_cp_apap_wRPEXgJRekaAc

If that's too expensive for your price range just do the strips or the drops. Waaaay more reliable.

u/willpower870 · 2 pointsr/Homebrewing

Supposedly the probe I use has ATC. I've tested the same sample at mash temp vs 60 degrees and got the exact same reading. YMMV

This is what I have:

u/Strel0k · 2 pointsr/Hydroponics

Bok choi has been the easiest thing for me to grow by far so there's definitely something off in your system.

Having a pH pen and an EC pen is pretty much critical to diagnosing nutrient solution problems. This is the pH meter I have, which is kind of mid-tier but comes with calibration solution. Also pick up some storage solution as it will reduce how often you have to recalibrate the pen vs keeping it dry. EC meter you can go cheap on, I use this one and get good results.

u/bender0877 · 2 pointsr/Homebrewing

For what it's worth, I picked up this one and it's been great.

u/wQuestionAsker · 2 pointsr/cannabiscultivation

Apera Instruments makes very very good ph pens. I’ve had mine for many months and I’ve calibrated it 2 times. I didn’t even need to calibrate it the 2nd time. I just wanted to see if it was off after a couple months, but it was still good! It’s still correctly calibrated right now, which has been another couple months since I did it last

I know some people use the cheap 15-20$ Orange and yellow ones amazon has with some pretty good results. I would personally spend a tad bit more and get one from Apera if you can.

Here’s the one I have: Apera ph20

u/kowboycillers · 2 pointsr/microgrowery

Just received this ph meter today:
https://www.amazon.com/dp/B01ENFOHN8/ref=cm_sw_r_cp_api_-iXpzb0Y5RXN0

Was really easy to calibrate and not too expensive imo. Will update with any issues, but so far it's perfect for my needs.

u/HighsaacNewton · 2 pointsr/microgrowery

I got this Apera Instruments pH pen style meter. It was about 0.2 out of calibration after ~2 months of use, it takes about 30 - 45 seconds for the pH to stop slowly changing... really annoying. It's fairly reliable but slow. Overall I'm fairly happy with it as a new grower, definitely meets my needs.

u/GERONIMOOOooo___ · 2 pointsr/hotsauce

Spring for a pH meter. This one comes with a full calibrations and testing kit for about $80. Here's the same one, without the extras for about $45.

u/EngineeredMadness · 2 pointsr/Homebrewing

First off, in order to use a pH meter, you must calibrate it every. single. time. Or at least once a week. They're notorious for drifting even when stored correctly. You will need 4.0 and 7.0 calibration solutions, they're sold as powder or in liquid form. You should also have probe cleaning and probe storage solution. Contact lens solution (not hydrogen peroxide stuff) can work as probe cleaning solution in this context, as it works well on organics in a gentle way.

Unfortunately the $10 specials aren't really that great, and you won't get really repeatable results until you hit about the $35-$50 price point. At this price point they should start to have replaceable probes. e.g.: this or this . I'm pretty sure /u/chino_brews knows the specific generic design name of the 2nd one I linked, lots of different vendors have a house brand white box version of it. Fisher Scientific design that went off patent, can't remember the number.

u/ClosetCaseGrowSpace · 2 pointsr/microgrowery

The only way I know of accurately testing pH in the soil is by testing the run-off from your waterings with an electronic meter.

u/b8nn8n · 2 pointsr/gardening

The meter is a matter of preference. I would shop based on how it's calibrated...some use 6.86 and 4.01 solutions but meters that calibrate at 7 & 4 may be more expensive but those solutions are cheaper. I have had probes break too so don't go crazy on price. I like this one because of the case it comes with along with the calibrating fluid. I would also get some sort of dropper it will help to adjust your ph. If it is just clean water a single drop of ph down will lower the oh by several points. Aim for 5.5-6.5

Draining and replacing the water won't solve your issue right away. As long as the plant stays alive and growing it should be fine. If you can remove the plant out of the bucket and run some water over it for a few minutes and replace the water it would probably help.

Edit: found a photo of my tomato last year. This thing got like 8ft tall.

u/420skyhigh · 1 pointr/GrowingMarijuana

Yes the flushing should help. I think the biggest issue with MG is the fact that new growers tend to overwater and such so that would affect the way the nutes are distributed to the plant. For a pH tester I use this . I pH the water before watering and then pH the runoff. I use coco/perlite mix so my pH levels will be diff than the ones you’d need. I also use distilled white vinegar to lower pH if needed instead of the pH test kits.

u/9babydill · 1 pointr/microgrowery

I bought too many of those cheapo $15-20 PH meters that failed too often. I'd recommend https://www.amazon.com/gp/product/B01ENFOHN8/ref=ox_sc_sfl_title_5?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

u/Dirtdigglr · 1 pointr/microgrowery

For the PH meter I am very happy with the Apera and it comes with calibration liquid.

I bought the one you have listed and it wasn’t even useable.

u/Bigfamei · 1 pointr/microgrowery

YOu can pick any ppm meter. That are many solid one.

As for Ph meter. I liked this kit I bought. Extra batteries, lanyard and solution to keep your meter calibrated.

u/estrogenix · 1 pointr/microgrowery

I’m on my first grow right now too. Very similar setup the only thing I’d suggest if you have the money right now is a digital PH meter something like this

Don’t be afraid to ask for advice if you run into problems this community is great. Follow your gut too, to an extent. I followed advice early on that was for soil and not coco (letting the coco dry out significantly before irritating again) some people will say this is how you do it, some say don’t, for me personally it was doing harm so I listened to those saying not to let it dry out. So far my plants have been hardier that i figured they’d be!

u/IDoMindTheDudeMinds · 1 pointr/microgrowery

Eeeee.. I have zero experience with kits like that. I use [this one] (https://www.amazon.com/dp/B01ENFOHN8/ref=cm_sw_r_cp_awdb_t1_XV2MDbSQ7ZA6Y) since [the one I bought originally] (https://www.amazon.com/dp/B01N20ZRC5/ref=cm_sw_r_cp_awdb_t1_jX2MDb2AKB2N4) was wildly inaccurate.

u/FiveYearAccountAlt · 1 pointr/Autoflowers

In that size tent I'd probably stick with 3 gal. I'm getting ready to do my first autos in a 4'x2' and I'm probably only going to do 2 plants in 5 gal. Because when I did that with photoperiods (vegged 45 days) with lst and scroging my tent was absolutely full. Feel like 3 autos would get too big for the tent. May take a couple of clones in case turns out I have extra room.

You also didn't specify what, I'm assuming soil, but would help with nute recommendation.

Highly suggest getting recharge, even if just a couple cheap sample packs, it helps so much.

Also skip the $10 PH pens. Get PH up and down with the test kit. And get one like this Apera Instruments PH20 or the $80 Blue labs if you want to splurge.

u/FiftiesThrifties · 1 pointr/microgrowery

Apera Instruments AI209 PH20... https://www.amazon.com/dp/B01ENFOHN8?ref=ppx_pop_mob_ap_share

This is a really good Ph pen for around 40 bucks. Better than any of these cheap crappy pens.

u/Cannabalabadingdong · 1 pointr/microgrowery

I wanted a scientific grade instrument and found this pen for under 50 bucks and have been using it well over a year now; the only time it lost calibration was when the batteries needed changing. It gives quick readouts and comes with a two point calibration solution system along with a sturdy case with cutouts to hold everything. This is the storage solution I use to maintain the probe.

u/Spaceman_Spif · 1 pointr/Homebrewing

I just looked into buying one last year. There's not much under 40 that gives two decimal digits with good accuracy. I ended up inheriting this one that is $97. I'm not convinced that 2 digits is necessary for brewing, but I'm very happy with the Hanna.

If you're just getting into water chemistry and are looking to save money, I'd go with something like this. Good luck!

u/Eliade1 · 1 pointr/microgrowery

Without a meter, you’re shooting in the dark. Unless you can find ph’d bottled water, it’s almost as good to power through it and do nothing. Here’s the meter I first bought (it lasted about two months). And here’s what I ended up with, and I couldn’t be happier (I also picked up a bottle of calibration solution).

u/aerogrower · 1 pointr/microgrowery

It looks like apera makes one that is not as expensive as Oaktons, and has better reviews than both Oakton and blulab. Ever heard of this thing?
