My ph is pretty spot on, never had a ph issue, so I think you’re right in saying mag def..
In your experience would you spray or feed soil ?
I’m using pro mix HP, feeding only front row ag line.
Can anyone give me advice on this? It looks like maybe cal mag toxicity or deficiency, can anyone confirm. Feeding all my plants the same nutes and this strain which is a master kush from Canada seems to need different attention.
