Hey good people I've been looking for this problem and have now spent two days without findings. Ok there are many issues on leave curling. But my leaves aren't curling so.to say. Just the very tip and not up down. So the very point or tip on each leaf is curled straight down im thinking some kind of lock out. But my ph is 6.4 6.5 there is some discolor on bottom leaves. Last watering 4 days ago. The only other thing that's going through this little brain is cold front. Im raised off the actual floor but it is a slab of cement. The weather has turned to fall we are having 40's in the night. I can't get pictures right now cause I'm in the turn and it lights out right now.there in total dark for a couple of hours all ready so im not opening until.tonight. open for any throught.. just any ideas. I know several of you have been growing for a long time so any of you have a one time one of my plants. Im open to hearing about it. You follow I knew that you could but would you.. not sure thanks and play nice with other when ever its possible
