looks like mag deficiencie foliar with epson salt.
Stop even looking at a feeding schedule and use a medicine measuring cup with 5ml marks. Plants will be perfectly happy with being lightly fertilized, not so much with being slightly over fertilized. I rarely give my plants more than 15ml total nutrients (2 base nute+calmag or bloom boost) and my plants always look happy. Fox farm calls for something like 45ml in one gallon of water at one point in their feeding schedule and that would burn most any plant. 5ml of each base nute and 5ml of calmag per gallon is a good starting point.I been using fox farm stuff for a long time seems its made up of salt lol so far not really had much luck growing thinking about just letting it all go
I use calmag and veg nutes the first few weeks of flower until the stretch is over and then switch to bloom nutes. This helps with the stretch and helps keep them from getting ca and mg issues because of the massive draw of nutes in the stretch.am I to use calmag in flower I thought that it was not to b used bc it burns them or something cant think of it off hand right now?
