Ok if your ph swing is handled I would find a good cal mag sup and feed it heavy and see what happens everything else looks ok

okay thanks!, I use canna mono cal mag and have increased the dose. the plants look a little healthier now but alot of leaves still looks infected so I only hope they wont die...
is it okay to put calmag in the res in the middle of the week even if i its not a ttal nute change or is that going to be a problem?
