nft hydro help plllllls
Theres some thing wrong with my plants they are twisting at the tips very brittle my temps are at 65 F ph is at 6 feeding is at 500ppm or 10 ,3 weeks into veg. The lights are at the right height just cant seem to get it right some hell. So pls if some ones got an ideal pls help me out. Could this be heat stress or nutrient or could it be the fan blowing over them i have heaps of fresh in coming in and extraction fan blowing out.
