Yellowing curling leaves? Please help!

I've been growing my northern lights plant since July 18th, and I started to flower on August 7th and she's a little over a foot (i know, she's small). Anyway, this started with her lower leaves and is working it's way up, the leaves are yellowing badly, and curling down on the edges, and she also has brown spots. I have already (completely) lost and disposed of 2-4 of her full fan leaves and it seems to be happening to the rest! She is in a pot with 1/2 part hydroponic beads and 1/2 part MG Moisture Control Soil, and she is nuted approx. every 4-5 days with MG Bloom Booster. Contrary to the fact that she is in hydroponic beads, she is not grown hydroponically, instead I water once a day manually. Her PH is at 7.0! Thanks a lot, if you have any question feel free to ask!

and

ph should be in the 6.5 range... bloom booster is only useful during flowering, your vegging, so you need nitrogen.

I'm actually flowering, not vegging, so does that mean that the bloom booster is good or bad? And thanks for your answer!
