Ok so it’s an odd one I’ve not seen before but I’ve got one single leaf that turned yellow. Nothing looks wrong, it’s growing like a champ only this new set of leafs has one that’s all yellow. Pest maybe or a coming nutritional need that’s coming? It’s in Poundhouse super soil getting ready to flip so I repotted 2 weeks ago and it’s in the winter mix in 7 gallon nursery pot, under SK402, 2 x closet case 100’s each plus 1 MLH @ 100 watts too. I keep humidity at 70% for now until flip at 84.7 degrees on average plus CO2 at 1100 ppm. So all plants are rocking, just odd leaf?
