I have never had this problem before, it's only on 3 of my plants in Flowering.
SoilMix - Sunshine Number 4
Nutrients - Humboldt Master A and B
Lighting - 1000 W HPS

The leaves are curling down, and look very leathery, yet are still growing, I know they are not rootbound, as they are in 5 gallon pots right now, and were transplanted before flowering, this is only week 2 of flowering. My question is what could be the cause? I thought it was over watering, so I let them dry out and gave them regular Ph water the next 2 waterings, yet I have not seen any change.
