Day 13 after sprout-rockwool insertion, leaves were only slightly yellow this morning, (use a 150w LED at night) and lemon juice to lower ph. What am i doing horribly wrong? Is sunlight too much for it?
any way to reverse the effect?

i've bought a 240w drgrowrite led and 6.5'x3'x3' tent
(rubbermaid tubs look too small for 2 plants) it seems that bibbleponics uses a better oxy stone and dual pump?
