hempy grow-switching to flower - nute advice?

allright, here's my current setup in veg--
9 fem white queen
5 gal buckets, cut down to maybe 3-3 1/2 gal
hempy!
100% perlite
1000 MH, recently added 6 100 watt cfls
veg for 11 weeks so far
i give em-
6 ml GH floramicro
10 ml GH florabloom
5 or 6 drops of neem oil
1/2 ml superthrive
1/4 ml calmag
4 or so ml of hygrozyme
ph up/down when needed
all amounts go into each gallon...i feed em every other day, i mix up 3 gallons and disperse nearly even among all 9 plants, i recently made up 4 gals, and they were a little weighty still after 2 days...
to me it seems i am adding quite a lot and throwing a ton of ppms in each gallon...no ppm reader...
i usually use 2 or 3 day old sitting water, distilled a couple of times.
ok, here's the stuff i have for flowering-
same GH micro/bloom, but i'll stick with the lucas formula and use 10/16
-discontinue use of superthrive
-i have a big ol jug of AN overdrive
-picked up a 40 gram bag of AN bud blood
Dutch Masters reverse
Dutch Masters zone

first off, not sure if i'll need the calmag anymore, i figure 1/4 ml can't hurt much...probably still use neem oil ($16 for a little ass bottle!)
using feminized seeds, i wanted to get some reverse...i have a litre, and it seems to go quite a ways, but my plan with the reverse is to spray em down with it around week 3 of flowering, then again 10 days later, not even mess with missing a male sac...does anyone who's messed around with this stuff a lot know if reverse works like that? preemptively striking and all?...

i have 2 4 inch fans inside 4 inch pvc tubing, sucking air from an a/c, but i'm lucky to hit 82 degrees...i had a problem with green algae in my perlite, but with hygrozyme, the algae eventualy cleared up...from what i've read, zone is supposed to be the shit, just trying to get some feedback from someone who's used it...

one of my main concerns right now is eventual salt build-up. when i have been watering, i have not been watering til runoff (and missing out on a partial flush). when i first transplanted into the 5 gal, it took almost 3 times as much water to runoff as i'm feeding currently. after FOUR days (after watering 4 gal hempy til runoff) there was a ton of water in there, i even tipped the 5 gal to drain out all i could, ended up not needing to water that one for a week. there is no way i can have sitting water for days and days at a time. my temps are routinely hitting 90-92, and my room really doesn't bug-proof all the way. just last week during a feeding i added an extra 15 oz of water, and i went an extra day before watering, so i know adding almost a gallon of water is not going to be gone in any short time.
i'm thinking my best bet would be lower the res hole down to maybe an inch or so...but so far, after, i dunno, a dozen-fifteen feedings, there's nothing showing as far as a salt buildup, no nute defs, nothing...so i'm also thinking maybe plan on flushing twice or more during flowering...

bottom line-anyone who knows anything about what i'm talking about reply back

First off I know nothing about reverse so I will not comment on that. Secondly - Why are you adding all that crap in your nute mix? Cal-Mag, Superthrive, Neem Oil, Hygrozyme, AN Overdrive, Bud Blood, and Zone - WOW! General Hydroponics Flora Series nutes has everything in it to grow exceptional plants without adding anything else. And your lucas formula is wrong - it's 5/10 in veg and 8/16 in flower not 10/16. I would not lower the hole in your buckets to 1" - Hempy has proven that 2" works the best. I've been growing in hempy buckets for a couple of years now - although I use hydroton instead of perlite - and I never have a problem with any of my plants needing anything. I've been through the additive crap like everyone - and found just using flora 3 part works just as well and cheaper on the pocketbook. Every watering (every other day) I water until it starts to drip out the hole - with perlite you can get by with every third day because it holds a lot more moisture than hydroton. Every two weeks I water with plain pH'd water to avoid any salt build up - GH has a feeding schedule for drain to waste on their website. By the way - I don't use the lucas formula - I prefer the 1-1-1 ratio for veg and the 1-2-3 ratio for flower. Hope that's helpful.
