Calmag deficiency?

Hello all
currently growing Autoflowers growing in coco. 3rd week into flower.
Ppm around 650-750
Ph 5.6-6.0

Any help appreciated.

Just incase. I did flush this plant last week because I had salt build ups and really low pH run off. Like 4.9 low.

But here are the pics :)

I wanted to say that a plant can have either a calcium deficiency, or a magnesium deficiency, but I have learned not to classify them together as one problem. From what I have learned here, there is no such thing as a 'cal/mag deficiency. For me, I don't see either one here. Perhaps the salts buildup and the low PH caused your problems, and you might have already fixed it. Maybe wait a day or two and see what happens now.

If anything, the solid yellow leaves are showing a nitrogen deficiency which the low pH would have caused. I do see some rust spots on some leaves, but that can also be from the plant not up taking the correct nutes because of the low pH. Might as well prune off those yellow dying leaves, they won't come back. I would keep an eye on it for a couple days, watch new growth and see what these leaves look like. I wouldn't stress too much about it. If you corrected the pH they will spring back :) Good luck!

Did you rinse the coco well before using it? I’m not interested about any claims on the package saying you don’t need to. Soak and pretreat with cal mag.
