If you don't see any pests with a scope under leaves or elsewhere, i'd look into watering habits. are you allowing it to dry between irrigations? if not you may have some rootzone issues that can cause stuff that looks like this. Allow 1" up top to dry. Irrigate so that entirity of pot gets saturated -- no dry pockets. Some runoff is inevitable, cast it off.

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Brown/yellow/purple leaves in This started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today. I'm not worried at this point, just really want to know what's happening
