Question about my SCROG..?

[cheesypeace]

Ok So I currently have a 4 plant SCROG going 3 Northern lights and 1 KAHUNA.

KN NL
NL NL

That is the way they are arranged. They are day 15 of flowering and all of them have already started budding NICELY!! The SCROG is 3x 4 feet and made with chicking wire and a homade wooden frame. So I am wondering about nutes and stuff, They are all in 5 gallon bubble buckets and have a ph of 1000-1200 using 3 part liquid fertilizer (a,B,powerthrive).

So I am wondering I want to use some bloom enhancers also I am trying to increase the ppm every week but I have been slacking on the PPM raises.

What should I bring the ppm up to?
I counted and the scrog is full and has 100 tops that look like thumbnail size buds everywhere and I use 1000 watt hps with walls of flourescents on 2 of the sides for SUPREME LIGHTING hehe=]

How much will each bud weigh in six weeks at harvest time?3-4g's each? And will increasing the ppm help increase the yield by helping them produce??

Also I want to use the bloom enhancers at the hydro store, is it safe this early??

Any help please, I will try to get a camera but I dont have any pics yet.. sry..

ANY COMMENTS OR HELP PLEASE!

There are really about 3 or 4 stages of blooming, each of which should have different nutes.

Check out Fox Farms 3 stage bud enhancers, Beastie Bloom, etc.

in flower, i use cannas pk 13/14. it is at around week 5 you use it for one week. you reduce your base nutes to be able to add the pk booster. it really does a nice job.
