I need your help

As i see your fertilize methods i can surely say stop to mix minerals with bio fertilizers. If u using bio product you have to feed your microbes and bio living inside of the earth. If you mix up spicy chem fertilizers on bio you will destroy some of the bio living. Even if u use it not directly mixed. The fact of destroying will stay. I cant see any calmag def. I would more think about kalium at this point. Calmag has typical optics on the leave. You will have neon green coloring inbetween the leafes not a yellowish around. They do habe maybe to much water as well as they let themself fall down. If your pretty darkish leaves have dark purpleblackish spots which will burn out you have 100% Kalium def.

Potassium and/or zinc deficiency. This is not a cal/mag issue. Either add a P/K booster to your line up or increase the dosage if already using one and/or give a dose or threee of a soluble trace element/trace mineral mix to your plant. Trace element mixes are available from any decent garden centre and will only benefit your plant positively, even if it is not zinc related.

I don't see any issues resulting from to much or little of Ca or Mg, The edges look like K issues to me. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg here's a leaf chart to reference. Would look into the PPM or EC of what you are feeding and the ratios of NPK and its PH. Could be buildup, could be PH issues could be both. Good Luck!

Way too much juice Bro. Ladies don't like when you blow your K early.
