I have a few questions about my current grow. I'm growing in straight Coco with fox farms grow big. I ph my water/nutes to 5.8. I've only fed them a few times so far and I water them until I get a good amount of runoff each time. Temps are usually 69f-77f but my humidity is low (30%). There's 3 different things wrong. 1- the spots on the leaves 2- the cupping leaves mainly on 2 of 5 plants near the top+ middle (i figured theyre too hot but its only half of them and theyre all the same exact distance from the light and the cupping ones are closest to the fan). and finally 3- there are leaves twisting. I thought that might be ph but I always ph to 5.8 and my meter is calibrated every time. Any ideas?
