Hey there dzdr. IMHO it's call mag def and if not checked it will destroy a plant. Its something I deal with every grow. Partly due to using R.O water and not providing calcium and magnesium which is filtered out . Also could be caused by pH imbalance leading to lock out. The good thing about cal-mag supolements is it's hard to over do it. Also check out the stems of the leaves and smaller branches if purple or violet color are showing it's a sign of cal mag def. Hopeful this will help my friend.
CHEERS!!!

Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

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 inThis 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
