So I made a new thread please take a look at the new pictures these spots started after the plant went into flowering. It is now 5 weeks into flowering. I have two more that just started flowering that are allready showing spots for the past week. What should I do. This is not spider mites! It is DWC recirculating setup. Using GH Flora, ph is 5.5... good air circulation etc..
Reminds me of a potassium dificiency. Try flushing it the medium with three times the volume of water for the volume of the medium, than add another complete fertilizer. However, it may also be a maganese deficiency. Not quite sure at this point, have anymore pics?
it dosent look like mg, it def could be potassium, or PH, like the guy above me said flush the soil however on the last gallon use 1/2 strength nutes, not full
