First grow seeking advice!

My lower branches/buds seem to be getting lots of shade from the upper big leaves. about 20% of the hairs have turned red, so im guessing 3 more weeks. Should I trim the big leaves and give more light to the lower buds?

NO!!! sugar factorie's supporting bud growth push them under the bud's they cover!!!

I have 4 plants about 3-4 ft tall. 400w hps 150w hps and around 500 more watts in cfl and fl lights. Is that enough light?

Never remove a leaf unless it's completely yellow...

jarmstro - you have plenty of light. Generally, the rule is 50w/sq ft.

There seems to be a lot of drooping on one of the plants. theyre in 3gal pots. is that the problem?

No, never remove a fan leaf, plants need them to grow, would you cut off you arm if it was in the way?

"Should I trim the big leaves and give more light to the lower buds?" No. Fan leaves help the plant turn light into energy for growing.
Cutting off too many will turn the plant white and the product worthless. In fact, the more fans on the plant the juicier the nugs.

With 20% red pistils your finishing time depends on your light source. Under my 1000W flowering bulb I would expect that plant to be
finished in a week. Maybe less. I believe any light stronger than 400W will finish her in less than 2 weeks.

Jus keep tucking fan leaves under them buds...
