Are this brown pots a lack of potassium, and could it be caused by us giving to much Calmag?
bluecakestarted grow question a month 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.

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.

This chart can help.
Good Luck!

Autos reacting to All-Mix: Slight nitrogen overload?Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Strange discolorationThe 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.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.
