Just came back from a short 3 day trip and noticed that all my leaves are literally covered with little rust spots and they are beginning to curl under like a claw (just a bit). The leaves are a dark green and there is no sign of yellowing. The roots are massive and completely snow white. The pH was about 6.1. She was in a 3 gallon bubbler bucket with tiger bloom solution at the rate of 3 tsp per gallon.. Today is week 5 of flowering. Buds are very big and will be needing some support soon so at least this problem is not effecting the buds.....yet. Right now I have her in plain water at pH 6.2. I thought it might be some sort of nute burn so that's why I put her in plain water. So far there is no change. Does anyone know what could be causing all these rust spots?
