I have one plant that's kinda strange with how the leaves are,, it's planted in a fifty fifty mix ffof and happy frog on bottom half of pot, then filled up with straight happy frog, in five gallon smart pots,, the plant with the issues has never been feed yet, just ph adjusted water at 6.5, running a 315 ceramic light temps are high of 83 low of 74, humidity of 40-55,, other three plants seam just fine,, the two bigger ones are Hindu Kush and have had two feedings to date I'm using nectar for the gods, the plant with the issue is a sour crack, the other small one is a sour crack also and looks fine
