i can say for sure that looks to me like you over fed her.
one thing to remeber somewhat related
ive been growing over 30 years, never bought any of the "specialty" products. ive found years ago that their nute contents and what they do are virtually identical in most cases to what you can buy off of the shelf at the local hardware store or nursery, and at a HUGE savings. do some checking, youll see what i mean. not that im bragging or anything cause im not, but using off the shelf products, most of the weed i grow is usually one hit shit. some of my stuffs been so potent that even veteran smokers are hesitant to smoke it or to take more than 1 or two hits because they know from experience that my stuffs been known to make them unfunctional for 2-4 hours. BUT that all makes not much difference if your growing hydro cause im a dirtyboy myself.
