I'm not sure if this is a nitrogen deficiency or a lockout situation. I foliar fed a few days ago and got some very light burning. I sprayed heavily but the mix/ratio was recommended. If anything a little weaker than recommended.

I run a top feed drain to the reservoir hydro setup. EC is 2.1 when a fresh batch is mixed. I add water as they drink and this naturally dilutes the nutrient solution. Once it hits about 1.2 EC, I will add back to bring it to 2.0-ish

Chilled water to 65 degrees, lights are 65% at 18-24" above. Controlled and sealed room. 80 degrees with 70% RH, 1000PPM CO2


THOUGHTS?

In my opinion they look good but also in my opinion those yellowing leaves want to be removed so it’s starting the removal themselves but this is my limited knowledge an my thoughts only . Something fir you to think on maybe

try this pic. Everything went from nice green to almost a lime color in about 48 hours. Obviously these are the worst looking of the whole grow.
