Yellowing dying leaves!

I've been growing my northern lights plant since July 18th and started to flower in august 13th, now she has been yellowing from her bottom leaves up and 3 (full) fan leaves have fallen off already! Her leaves have dark brown spots on the edges and are drying from the tip up the leaf, they are a pale-yellow color. She is in a pot of %50 hydroponic beads and %50 MG Moisture Control Soil, and I water her once a day. I nutrient her approximately every 4 days with MG Bloom Booster half strength. Her Soil Ph level is at 7.2, and her water Ph level is 7.0! She is about 1 1/2' away from a 400w HPS light w/ reflector. I water her about 6 fl. ounces each watering. If you have any questions feel free to ask, Thanks a lot!

if its yellowing from the bottom it is most likely a nitrogen deficiency. Pictures would help make a better diagnosis.

i think i responded to your post before. You are giving your plant bloom booster... Which in turn is simply Phosphorous and Potassium. Your plants needs nitrogen, and your not providing that. Your leafs are dying from the bottom up... which means the problem is a mobile element such as N. Your soil PH level is way too high... your pH should be around 6.5 give or take. Some pictures would be nice also

i had a similar prob wiv WW am my next grow wiv same seeds and am avin similar probs to urself, but i av a other variety in there that shows no adverse affects so i am leaning to think my WW are prone to this shit, but anyway, my last grow i lost a lot of leaves, fan leaves also n still one plant gave me 4 dry ounces of shit hot bud so all aint lost m8 thats for sure. grow on get the ph down a tab and see how they go,. coz gettin to the bottom of any particular problem aint easy to diagnose on places like this unless its well obvious, but it sounds like lack of N but the fact ur like 6 weeks into flower ime sure it wont hurt to much the loss of them leaves coz i lost a shit load round the stage ur at now flowerd on for 4 more weeks than where ur at now and like a sed it was good shit n plenty of it. good look man !

watering every day might be a bit much? if you're drowning it in high-ph water, maybe it is locking out nutrients.

Thank you very much for your answers, here are some pics:
