After experimenting for 2 years with Advanced Nutrients/additives...
Botanicare Pure blend Pro/additives...and GH3-part/additives.
I fond this formula works and yields the best; And leaves the roots healthy throughout grow. Goodluck

This should answer a lot of question's you newb's have, and It should save you some money in the longrun.

Since a lot of you get caught up in the Lucas Method. I found this to yield more. However if you have space limitations, just remove the Grow from the formula for smaller plants/yield

START>>>Here is a higher yielding alternative to cut and dried lucas method...
Use grow part in veg 1-1-1 and create high yield bushes=less plants=less trouble, same yield overall.
In flower...use squewed 3-part
.25-1-2 for 1st 4 weeks
weeks 4/5 revert to lucas 0-1-2. Cutting the nitrogen back.
High yield philosphy...Grow bigger, but less...

From 35 gallon rez I dip a 5g bucket and add nutes. I have a turkey baster syringe that sucks up exactly 40 ml if you fill it, So that works perfectly.

5 gallon formula...convert as necessary...

Starting with reverse-osmosis water

Values:
1=8ml,
8ml per gallon
5g=40ml

Veg 1-1-1 = 40-40-40

Flower .25-1-2 = 10-40-80

Finish 0-1-2 = 0-40-80
------------------------------------------------
Veg:40-40-40

add calmag+/3-5ml per gallon **ph5.8 water for topoff's in between nute change... I do not use calmag in nute change solution.
So. I am doing what you are doing except I don't use carboload, I use Liquid Karma/or Seablast/ or some type of Vit-b and sparingly (this stuff cause all kinds of foliage. (Especially under-foliage and I find the too much under growth can causes airflow, and pest problems)

Use LK/Vit-b as I do Calmag+ for topoffs's in between nute change. Alternate topoff solutions each cycle; switching out LiquidKarma for Calmag+ every other week in between your weekly nute change (every 7-10 days).

Example: 3-part, topoff CM+, nute change 3-part, topoff LK, nute change 3-part, topoff CM+...etc, etc.
hope this makes sense.
------------------------------------------------
Flower stage:
Start off with all 3 parts
same value=8ml x's 5 G's=40ml=1 part

Campared to lucas 0-1-2/0-40-80 for flower...
Use .25-1-2/15-40-80 per 5 gallons. You get more mass using the nitrogen at this stage.

It is safe to say this is close to the Advanced Nutrients values, but I simplifiied the recipe by going to GH/lucas values
Actually, they are General Hydroponincs values...right off the bottle. tweak as you need.

In week *4/5 flower. I switch to 0-40-80, and continue alternating CM+/LK topoff process. I topoff at least every other day. this is PK boost time for 8 week finish, I just use clean 0-40-80 until PK transition. so for 9-12 week finish you would hold off on PK/Overdrive, whatever...
Use Overdrive, or high pk formula for a week or 2 prior to final flush.

Flush w/Florakleen.

*week 4/5 of flower. drop ph to 5.4 to make PK nutes more available to plants. increase the ph each week .1... i.e. wk4-ph5.4, wk5 ph5.5, wk6 ph5.6, wk7 ph5.7, wk 8 5.8 finish...Again; If you require longer finishing time, You hold off on this ph transition.
**most of the time, calmag+/LK will buffer the water's ph and you don't have to adjust.

So that is my take...I don't even right it down anymore. I just go with the flow. Sorry about rambling on, but I figured I could go ahead and copy/paste this explanation to my notepad for publication on my hydroponics website.

I invite You to come over to: http://hygronomics.com/forum1 post some hydro question's there, help me build traffic there, and everyone can benefit form the knowledge gained. We can discuss all the hydroponics you want and countless other topics.
