Your problem is the fertilizer. You have bloom nutes that you are using in veg, so they probably arent getting enough N. Also, you shouldnt start nutes until the cotyledons are turning yellow. This is fixable though! Just stop feeding her nutes for now and get yourself some veg nutes (GH Trio is a set of 3 that's great for veg). You will also need some CalMag and I recommend hydroguard for the roots. Good luck friend!
