Welcome
I have a problem with my leaves on mid stage of flow - as on pictures. These are moby dick XXL's on coco. Nutrients are Dutchpro A+B and Advanced nutrients additives - cal/mag bud candy big bud etc. as in AN chart is specifie.
Im using RO wather, ph 5.9-6.0. It looks a bit like Mg deficiency due to Ca overdose but im not sure and dont want to do any more harm.
Am i right with Mg deficiency?
cheers
