That is the wrong way to learn about growing. It's costly and slow. Just watch some YouTube videos and go try. It's how I got started. I knew 0 about growing anything 6 months ago. Now I've got a successful crop and have a single tomato plant with over 20 tomatoes on it and many bell peppers growing, okra, pablano peppers, raddish, lettuce, basil, potatoes, kale and brussel sprouts. I've only spent about $200 too.

Cheap good EC meter (EC is shown in μs/cm instead of the more common ms/cm, as in above link, so the EC shown should be divided by 1000 to get normal EC numbers; it's easy, just remember when it shows 2300 EC, that's an EC of 2.3, or 700 is 0.7. Also note I've found with all these EC meters you need to dip and then swish them around in the solution and then read it, otherwise it will read inaccurate due to tiny air bubbles on the probes) https://www.amazon.com/gp/aw/d/B01FPG89CE?psc=1&ref=ppx_pop_mob_b_asin_title

Easy micro greens, which you use to sprout seeds you want to grow or eat as micro greens:

ReUse 2 disposable plastic food containers, a cheap poly wicking cloth, and your choice of grow bed (dirt, coco coir, whatever)...

Stack the two containers.

Make 2 long cuts in the bottom of the top container thru the lid of the bottom container, along the 2 longer sides.

Push the cloth thru the 2 slots, such that it's layered across the bottom of the top container and the ends are hanging in the bottom container.

Fill bottom container with water.

Place grow bed material in top container on top of cloth.

The cloth wicks up the water and keeps the grow bed moist. You don't have to water it but maybe once every two weeks and can leave the micro plants there for staging plant growth every couple weeks cause they will grow slow. If you don't use dirt as the grow bed, you will need to replace water with a weak nutrient solution after three or four weeks.

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.

Test your tap waters ph,tds, gh and kh. Here are shrimp parameters . If your tap water isn’t ideal I would recommend doing the ro water with a remineralizer.

I don’t think stratum is worth is for neocaridina shrimp since they require kh in there water. The kh will run the buffering real quick. For neocaridina I think sand is the best substrate.

I would highly recommend looking at different types of mosses there’s a lot of very cool ones besides java moss.

Get an EC meter and PH meter and just feed at 1.5 EC your plants will tell you if they are lacking something and you can address then. If you have a solid nute base and maybe some calmag you should have no problems

Base Nute https://www.amazon.com/General-Hydroponics-FloraNova-Bloom-Quart/dp/B000W7C87Y
Calmag https://www.amazon.com/Botanicare-Cal-Mag-Plus-Quart/dp/B004JKBMRW/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1481303031&sr=1-1&keywords=calmag

With the above base nute follow the lucas formula and you will have above average results with good genetics and paired with a hempy bucket you will kill it

I've heard a lot on here, and online, it's pretty common for your first batch to die off, the key is if you have babies or the first batch has babies in your water, if the water is in the acceptable parameters that you say, will be born and used to your water and will thrive. I just recently started and my first batch all died I got from my LFS then I orders 10 from shrimp farm .com and it came with 2 extra, and I almost didn't notice it came with like a dozen, must've been born a day or two before shipping or maybe even on the way, baby shrimp smaller than a grain of rice. All of them are still going strong and I have 3 berried females right now. Of that batch I've lost 3 or 4 adults.

Edit: also saw your looking at getting a TDS meter off Amazon. Be selective in what you choose, I got a couple on there I returned because they were giving me extremely adverse / fluctuating readings all the time. You want to make sure you get one that has ATC, Automatic temperature calibration, or something like that.

I got this one and verified it still my school chemistry lab testing their tap water, RO water, and DI water and compared it with their readings and it was pretty darn close.

It's out of stock right now it looks like through Amazon? May be available through other sellers or sites ?

Is there a tool that can give me the PPM for N-P-K?

I ordered these.

for PH i own this one and i bought this calibration solution.

For PPM this guy.

People highly recommend BlueLabs however, Im poor and these work LOL
