I would say to add a little more cal-mag and keep your grow at the same rate or slightly less than previous feed. The coco unless buffered with cal-mag will battle the plant for it resulting in the upper yellowing. The extreme darkening of the leaf almost blue looking is a nitrogen excess. happy growing!

Catching a fade?Is this fade normal for a Crème de la Chem? Or is this some other kind of deficiency. This plant has not had any issues. She’s the most healthy of all of them. In the pics I’m trying to illustrate the purple color showing up on some leaves.

Strange discoloration The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Purple stems-curling tips leaves point down Guys the sides stems seem really purple!even the central stem.. Why? magnesium deficiency?or genetics? And that leaves tip pointed down; they are a problem.. Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

Leaf underside Veins going purple So the plant I was worried might have a cal-mag deficiency coming on had slightly more yellow leaf middles and undersides. Tonight those have all started to go a deep purple color like some of her fan leaf stems. Does anyone know if this is common with the Forbidden Runtz?
