My plant leaves are yellowing at a very early stage of blooming and I'm not sure why. First picture was taken 8/24/15 and the second set is today's pic of the plant. The third pic is from a different plant and it's in week 4 of bloom.
I'm using Happy frog with perlite and peat moss. Feeding Maxsea bloom 3-20-20 with calimagic,molasses and bio-cozyme also I just gave them some verde for nitrogen. I don't check my Ph because this is outdoor grow I didn't check it last year and it was fine. The leaves are yellowing and turning into crisp.
