Hey all, newish grower here, legal in MI I have a recurring problem where the leaves, starting from the middle-lower ones, start getting rust spots between the veins that multiply and then the leaves yellow and die from the tips and margins. This has been happening to three generations now so there is a hole in my program. Nothing I have done has helped. Environment: 600w HPS 20/4 cycle 65* night 77* day RH is low, 28-34%...it is dry as hell 5 gal. pots, Pro-mix HP, tap water Nutrients: Ionic grow 2-1-2 and bloom 1-1-3 never at more than 50% recommended Green Fuse growth and bloom stims Tried adding lime and epsom individually without effect My camera is not great. This is a plant I have been vegging for awhile as a guinea pig (freebie seed). It was just topped, and tied down as an lst experiment. Only the top leaves are healthy, the lower ones keep dying on me moving upwards. I topped it aggressively because most of the leaves were dying on the main shoot, and to get 4 tops. I just don't get why some plants are affected in the garden and some not. The last pic is an autoflowerer grown the same way that was hardly affected by the spots at all. Could it be a mold? The guy at the hydro shop though it was blight based on my description.
