Well, other than calcium and related phosphorus, it might be slight potassium issue.

Red petioles, everything else good Hi! :) Does anyone have suggestions on the red petioles? They all turned red in flowering week 3, also the lower ones. I removed the secondary shoots and some leaves lately. Nutrition should be plenty, soil pH and EC are normal. temps are normal, humidity in a perfect range...

Brown leaves and red stems. Is this a calcium deficiency ?I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

dying top fan leaves All of my 3 plants are receiving the same treatment but one of them is showing signs of distress. Some of the top fan leaves are getting dry and brittle and dying. I thought perhaps the problem is I haven't been allowing enough run off?

Phosphorus deficiency? PH problems?I'm on day 56 of flowering, and only the Mimosa Evo's leaves are starting to turn red, pinkish purple. I suspect a phosphorus deficiency/absorption problem due to the pH being too low. Or is it genetic?

yellow/copper appearance in some leaves after first run off watering hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?
