Jose.gh Posted April 12, 2018 Share Posted April 12, 2018 Hello! It is complex to know, but at first glance, it looks like some kind of deficiency (magnesium - calcium?). Do you regulate pH and use nutrients? Link to comment Share on other sites More sharing options...

GreenQc Posted April 18, 2018 Share Posted April 18, 2018 I don't think its magnesium, but manganese deficiency. New leafs are more yellow and those spot are not on the side of the leaf. 1 Link to comment Share on other sites More sharing options...
Aquakush Posted April 30, 2018 Share Posted April 30, 2018 Calcium.....you need some Ca-Mg watch the pH change 1 Link to comment Share on other sites More sharing options...
Big'G' Posted May 13, 2018 Author Share Posted May 13, 2018 So I'm using cal-mag and voodoo juice and have great results no more of the brown spots. I'm going to add a phosphorus additive during the flowering stage as this seems to be what everyone is saying. 1 Link to comment Share on other sites More sharing options...
