If we are going to discuss this, we should start another thread so we don't take it away from the OP.

I did start a thread a long time ago but no one seemed interested so it died.

I'll see if I can dig it up and bump it.

There are a zillion sensors available for the RPi. Some are better than others. I'll bump that old thread and list the sensors models that I'm using.

A proper electron prob setup is $$$ to figure out NPK MG/S MICRO consumption. This is going to take
me some time to get i also need too build air tight grow chamber to control all variables and max
transpiration water use efficiency is very important to accurately log. I'm currently reading

The grow spectrum I will be using will be very different to most grow light.

I give my Respect!

Do you plan on sending in leaf and flower samples to a lab and have them tested for macro and micro nutrient levels on a weekly basis to help confirm nutrient uptake and usage?

Nice setup.

Figuring out the optimal nutrient concentration in hydro water solution is going to be fun! First I will be discussing the different nutrient I will be using to maintain nutrient concentration subject to change.

Base nutrient +chelated micros
-5-11-26 Peters Hydroponic Special 5-11-26 6-0-8

Supplement/Control nutrient
-Calcium Powder Amino Acid 5-0-0 0-15-0
-Ferti-Nitro Plus 13-0-0
-Potassium Nitrate 13.7-0-46
-MonoAmmonium Phosphate 12-61-0

Micro Boost
-Peters Professional S.T.E.M

Yes, macro and micro nutrient levels testing are important part of this.

thanks.
