Mg*
There are calcium deficiencies and there are magnesium deficiencies. Sometimes they both happen at the same time, however since Cal and Mag antagonize each other, you have to be careful about correcting deficiencies with "Cal/Mag". As an example calcium can cause a magnesium deficiency, while nitrogen can solve this deficiency, so adding extra magnesium isn’t necessary.
Looks like K deficiency, not Mg.My Apple Fritter mother has been looking not so happy recently, I'm thinking cal mag issue. It's a mom for clones, so it is in perpetual veg, but im not sure why this problem is happening as I haven't changed my feeding regimen but let me know what you think!
