I'm 13 days in since switching to 12/12. It looks like to me the fine hairs that are starting are yellow or turning yellow. I've got 6, 4ft Samsung strips pulling 630 watts from wall hanging 26" above the canopy. Does this look like the beginning of light burn or are the hairs typically lighter in color? Under the lights the hairs seem a little more yellow. It's much more noticeable on the taller plant. Let me know what you think. Thanks in advance
