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. Thanks a lot, if you have any question feel free to ask!

If your watering every day, you may be over watering regardless of the brand of soil. That is a classic nitrogen def caused by overwatering. Try watering every other day or even every 3 days. No need to give extra fert to fix the def.

moonraver knows what he is talking!

you gave it just bloom booster... so your missing the N in NPK. plus some yellowing is normal in flowerng
