Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?
Hi @Buddha2! Yes it seems so. You can add a slight dose of Cal/Mag in every waterings, until the issue is solved. In order to prevent such issue to appear, next time add Cal/Mag once a week into your feedings. Hope this will help, happy growing!
Hi there! You are absolutely right. Add it to your regular schedule. Myself I add it once a week. I grow in all mix soil / coco with 4/1 ratio. Looking very good btw!
Happy growing!
