Running a ebb-and-flo hydroponic system, 3 weeks into flowering. The bottom leaves look fine, but the top ones are getting these clusters of black/brown dots. PH is at 6.3-6.5 and I'm using CNS17 RIPE at 25ml/4 liter.
Searched and searched and got very little except for a Manganese deficiency. Any thoughts?
