Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Hi Legend, Not sure about it. Magnesium, Calcium, Ph. Maybe uptake or loss. She is growing well, big healthy. Ready for a second round of clones. After, I will let her sign in a bigger airy pot. Thank you for any suggestions 🙏

Leaf burnt edges
One leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

problems with clones!
Friends, tell me what's wrong with the plant! I don't understand it's under-feeding or over-feeding! At first I thought it was a cal-mag deficiency, then I saw a purple stem and thought it was a phosphorus deficiency! Now I don't know what it is anymore! at the very beginning it

Deficiency or ending cycle?
Hey! I was hoping someone could tell me if the first plant has a deficiency you would recommend I correct or if she is slowly coming to an end of her life cycle and I should just let her fade? The last picture is my other plant, less severe, but same question :) Thanks!
