600watt HPS hortilux , 5 gallon fox farm ocean forest soil, critical kush , adavnced nutrients fertilizers. very curious as what to may be causing my leaf problems around 2 weeks into flower and over the last 48 hours, the leaves on one of the plants has done this, curling up , brittle and discolored. I just flushed the soil after seeing them like this, any input would be appreciated.
