Salts building in your planter, causes lockout. Ph out of whack also causes lockout. Check both.

Brown yellow leaves?
Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Hey, few days before I noticed light green patches on leaves and now it's visible on more leaves. I noticed it only on large leaves now. What can be a cause of this? Also, I underwatered plant these days and maybe this can be a cause?
