Had some problems with rust, tried to fix with neem oil, and then i figured it was calcium deff, took a bit top much so chsnged the whole bucket which is a pain in the ass, now slowly i think its recovering, yook ph lil higher so calcium would be more available. Hopefully its not too late! Still some rust but i think it slowed down/stopped, also some curly leaves. But better now. Had to cut away some rust to see ot didnt progress! Ant thoughts? Ive taken 25% nutes but still have 340ppm and ec 0.7 in this 50l bucket.
