I wrote this article in 2006 for Cannabisdot… It was lost for the past 2 or 3 years, and suddenly, I find it posted as a sticky, once again @ Cdot. I hope you enjoy the read, and I reserve the right to change my mind on anything I got wrong back then. This is a great tutorial for all growers using H 3-part.
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
5 gallon formula…convert as necessary…
Starting with reverse-osmosis water
8ml per gallon
Veg 1-1-1 = 40-40-40
Flower .25-1-2 = 10-40-80
Finish 0-1-2 = 0-40-80
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
Example: 3-part, topoff CM+, nute change 3-part, topoff LK, nute change 3-part, topoff CM+…etc, etc.
hope this makes sense.
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,
Use Overdrive, or high pk formula for a week or 2 prior to final flush.
*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.
AND; There could be mistakes
