Are this brown pots a lack of potassium, and could it be caused by us giving to much Calmag?
bluecakestarted grow question 1y ago
We also discovered more brown spots on the leaves. You can see it on some of the pictures. We believe it might be a potassium deficiency, because we maybe added a bit too much calmag in the end? Todays feeding round we didn't add any calmag, and we hope it helps.

Probably a little nutrient lock out causing a calcium deficiency.
IDK why you add cal mag for soil. Coco - yes, soil, no.
Check and calibrate meter
Check ppm /ec under 2.0
Check ph (soil 6.5)
Calibrate those meters!

Potassium normally starts on the serrated edges of leaves not in the leaf itself. and it is not normally spotty like that.
I think you initial assessment of Ca is correct, it will take time to recover but should stop progressing, The existing damage will not repair.

Rusty spots on fan leaves overnight, what is it? ️Last night I used some old but clean looking wire to bring branches in to the main stems.
This morning there's now little orange rusty spots everywhere. Is a soil grow, 6.3 pH used and same run off with Cal Mag every other feed. Taken the wire of at 6am in anger, was it that? 😡

Hey, anyone got any idea or clue what's going on?I thought it was a manganese or iron deficiency from an early watering with high pH.
Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly.
She seems to be getting better slowly.. I think.
Thanks for taking the time. :)

Should I remove foliage affected by deficiency, or just let it ride?Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic).
1) Can someone confirm CalMag deficiency or something else?
2) Should I remove affected leaves or leave them be?
