I transplanted about a week ago to some different soil thinking it was soil PH. I'm using about 50/50 mix of topsoil and peat moss with perlite. I feed GH FLORA TRIO. Temps are 63-75 degrees, RH 47-63. I have them in 7 gallon smart pots. Issue didnt pop up untill i transplant into these smart pots so i tried to transplant again using some differnt brand soil and peat but issue has not stopped. I'm about 3 months into veg and I can't flip to flower because I cannot figure this issue out. It's been going on for about a month now. I added a few tsp lime in each pot about 2 days ago
