So this is my 2nd grow and my last one didn’t make it to the finish line unfortunately.. This one seems to have been going better but alas it started becoming concerning about a week or so ago. So just some background information some of the bottom leafs are turning yellow. When this started happening it was just one or two but now is becoming more prevalent. Some info it is Girl Scout cookies feminized. It’s in a 5 gallon pot in fox farm ocean forest potting soil.. for the past week I’ve been doing 3 teaspoons of tiger bloom, 1 tablespoon of big bloom and 1 teaspoon of cal mag in RO water that was ph balanced to 6.5. The ppfd is 710 and the light is 12 hrs on 12 hrs off. Temp is 72.1 f and humidity is 63% vpd 1.0 kPa. I thought it was nitro deficiency at first cause it was affecting the bottom leafs mostly. But I don’t know if I’m right.. so I clipped off all bunch of the yellow leafs but the picture im including are some leafs that are turning 1 in the middle the worst. Any help would be greatly appreciated and any question I will answer the best I can.
Thank you
