My nightmare first grow!

So my struggles are finally paying off my girls went into flower!!! Northern lights- did some low stress training to bring main cola down away from light. Added some vinegar in bowls and shot glasses to grow tent to control these flying knats(which bite). Pineapple auto- she's in flower I'm just concerned with all the lower leaf issue's that it's going to affect buds. I've over watered this plant which started the leaf issue's at like 3 weeks. At week 4 I trimmed all the fan leaves off which put it in stress almost haulting all growth for a week. Oh and the knats! I will never use walmart soil again for my grows or house plants. The neem oil has really knocked alot of them out. So the leaf burn and star leaves began at week 5 and it was the only feeding i gave my plants with cal mag and within 2 days the throwing star leaves and burning began.. not sure if it was the cal mag or the knats being so bad at that time. But thru all of it this plant has been a fighter!! You can see in pics the new growth and bud sights are healthy so I hope she fights all the way to the end!
