I'm feeding:
general hydroponics floraseries GH Kool bloom
Calmag+
Silica
A pinch of Epsom salt
And I also used Npk industries multiply thru out veg and that is a urea nitrogen supplement to promote growth. I haven't given it the multiply because I have some leaves with the clawing and I know that's nitrogen toxicity. Last night I gave it a half ml of that to see if it helped the yellowing
