Nitrogen? Light intensity ? Nutrient Lockout ? Magnesium Deficiency?

Alright guys I think I found it. Ive done a lot of research and checked out people with the exact same symptoms of the clawing leaves. So my Cal-Mag has high levels of Nitrogen that I was unaware about. About 30g/kg , and my GHE grow has around 24g/kg and my GHE micro has around 45g/kg. Now I supplemented 1ml of Cal-Mag per L water. And when I used Pre-Flowering dosages I used 1.5ml micro and 1.5ml grow (bloom has no Nitrogen). Ive been adding 1ml/L Cal-Mag since around week 1-2. Thus leading me to the conclusion that when I started pre-flowering I had the highest dosages of grow and micro and the extra Cal-Mag giving me a load of Nitrogen just before flower. Leading to Nitrogen Toxicity... This only badly affected my Orange Sherbets that were the smallest. My Gorilla Cookies somehow handled it but do have very dark leaves so im cutting out the grow and continuing with bloom and micro and then Cal-Mag. Now for the Magnesium deficiency I'll have to get some supplement that doesn't have that high amounts of Nitrogen. I figured Cal-Mag would only have Calcium and Magnesium but surprise surprise. Even tho it affects my plants, Orange Sherbet 2(my biggest lady) is flowering great regardless the Mg def. So the Nitrogen toxicity is more important to me now. I know that it seems like it could be overwatering or pH problems but I have grown in this medium before and its a really good medium. I don't easily overwater my plants(leaves would droop not claw) and affect fan leaves as well. My runoff pH was 6.1 and my medium recommendation for pH is 5.5-6.2. So pH is not the problem. My best guess then is N toxicity guys because I gave really high amounts of it without knowing really. Thanks for all the comments, it really helped narrowed the list of problem it could have been🙏🏻Feel free to tell me what you guys think.
