Going to agree with AsNoriu here.. you're overfeeding her quite a lot with too much nitrogen and you started feeding her far too early. Did you buffer the coco you used here? This needs to be done regardless of whether you mix it with other soil. Since you now have a nitrogen toxicity and a lockout of calcium, you need to flush - 3x the pot volume of pH'd water (since you're using a mix of coco and soil, get the pH to 6.0 which will be good for both). Then let her dry out before giving her anything more. When you do re-introduce the nutes, cut FloraMicro in half at least... it has a lot of nitrogen in it as does the FloraGrow and combined, this has been your problem. pH is going to be your biggest concern in this grow (as it is in ANY grow!) ... since you've decided to mix the coco and soil, I would think you need to be absolutely spot on with the pH and hold it right at 6.0 throughout the grow... Good luck! She'll come around - but sometimes, less is more!

nitrogen toxicity and lockout too rich soil or you started heavy feeding too early plain water with light calmag 0.25-0.5 ml/L for few times, then introduce feeding back, she was too small Your mix is interesting, i never tried, internet says that its beneficial, but to me looks like a myth, either coco either specialized soil. think ph issues could raise, because some coco needs good buffering before using . I could be wrong too ... Happy Growing !!!

Hi there To me she looks hungry and drawing nutrients from the leaves below .. At the same time she looks rich from nitrogen, Have you checked your feed doses and adjusting them accordingly every week as she gets older? Make sure she’s getting good light, Best of luck 🌱
