Swapping from sprouting 24 light to a veg 20/4.
Plant was fimmed. Yellow discoloration on lowest two fans; Believe due to light stress frm 24h light-> Switching to 20h/4h Sept 22d
Sept 23: First night of 4h rest seems to have alleviated sun stress. Plant was thirsty in the AM, drank lots. Pics are PM after leafs are full
