Try citric acid.

How long has it been like this because it looks like it's been there for 3 weeks

And cupping is from heat stress and your light may be to close I just went through this last grow

Especially if your bottom leaves stil look good

Most municipalities have hard water … hence buildup on showerheads / stucco walls / etc.


Easy to pull local water reports to see what magical muck flows from your pipes. Most can run from 1 to over a 100mg/L - water pushes through rock and soil, extracting their minerals. This makes the water “hard”. Hard water has high concentrations of calcium and magnesium.

No actually my bottom leaves are gone. The plant is like 6ft tall but about the bottom 2 ft just wilted and died. When i inquired about this, i was told its basically because the bottom leaves are receiving minimal light, so they checked out. But ive never really encountered that before lol. And ive grown some monsters in the past few years. It may be because the grow closet i made is a little tight so its not letting the light penetrate the canopy very deep but idk.
