No it's not signs of cal mag. It's signs of potassium defeciency, increase available bloom nutes and double check your ph
Darktideanswered grow question 4y ago
It may be a slight amount of PH imbalance affecting the uptake of magnesium.
Calcium deficiency causes brown leaf splotches.
Magnesium show light green or yellow on the veins or edges, almost like striping and typically has red stems.
I use the below to check on symptoms and help diagnose my plants as it covers most everything.

What is this rust discoloration on leaves, and how can I stop it?Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁
