GMSgrowsanswered grow question 4 years ago I think I read somewhere that gg#4 can have a twist to the leaves, although I am growing it as well and I have seen no twisting. Burnt tip might be from being a little high on the bloom nutes, they dont need as much as in veg, best to start low and vamp up if you see deficiencies, early leaf yellowing happening. Cheers
