on one of my plants the leaves are cupped under and drooping slightly but they are a nice green color. The other nine look great and are all standing at attention. I am feeding with FF grow and bloom 1/2 strength(1 tsp. of grow and 1 tbls. of bloom) every other watering, temps range from low 70's to 80 with 40 to 50% humidity. Does anyone have any ideas or pics of what this could be or am I just worrying.
