This is not looking good at all, every day I pick off different yellow leaves. Not sure what I'm missing but if someone knows let me know lol. Just gonna grow it out though, too late to give up on her.
Looking at your cupping in flower they look like they drastically need water. If you're only giving it 1 nutrient, it probably needs more food too. Try Athena if you're looking for an easy 2 part solution.
