Im noticing brown leaves on my baby buds

Im growing 7 grape punch plants 4x4 grow tentwith 1 sodium 1000w light. I'm four weeks into flowering. I used fox farm soil, and Alaska fish emolsion during vegging. Once i went to flower, i switched to earth juice meta K and big bloomin guano. Last week i switched to general Hyroponic Florabloom and have noticed a diffrence as far as bud growth. Today i started adding 1/2 tablespoon molasses to florabllom (Sorry about spelling, Im stoned) I feed about every four days, but notice on the fourth day, leaves are droopy. Once i turn off light for 12 hrs they are back in the morning. i also notice some brown and dying leaves that have purple stems. i think they are fan leaves. Is this normal? Please look at my pictures and give me any hints or tips s tohow they look. Ive also looked at them today with a 100X hand microscope from radio shack and trichromes are clear. I figure im about three to four weeks for harvest. When should I stop nutzing for taste etc. Can I still add mollasses up until final flaush about a week out? Any advise is appreciated since this is my first grow.

I can't see anything wrong but then that HPS is blinding any color variances you have.
If your near the last 4 weeks you should out ALL nitrogen and cut back on the P & K by half each week, the molasses you can do right to the end

Thanks farm boi. I'll cut my nutz in half each week until i dont nute at all the final week? The flora bloom is 5.0 phosphate, 4.0 soluable poyash. i dont think there is any nitrogen? are brown leaves ok?

your right on track with the nutes, get the brown leaves out of there, they're just trouble. I prune them out as soon as they turn yellow.

And how often should i nutz? im doing it every four days or basicly when i water. is this ok? should i feed once a week and water twice? i need advise on this.

ok will trim all yellow leaves tomorrow.
