Um... there's a GH chart over in the FAQs... let me see if I get the link...

Yeap... Here it is: http://boards.cannabis.com/showthread.php?t=25080

Look, the GH 3part you can use mainly in two ways: by stages (clones, veg, flowering) or by weeks (veg1, veg2, flowering1, flowering2... etc).

Or you can mix them with the Lucas formula or other one of those.

I follow the GH chart for weeks.

How to mix them:::

I had the same questions... so let's see if this helps.

1st, fill your rez, bucket, etc.
You have to add the GH nutes IN ORDER... or nutrient lock-out can occour... whatever the fuck that means.

First, mix the correct amounts of Grow... mix.
Micro... mix.
Bloom... mix.

How much? Follow the directions. They give X mL (or Y teaspoons) per US gallon. you just multiply/divide/etc. to get what you need.

After you've mixed everything, give it some time (1 hour?)... then check your pH, and adjust for pH.

You should adjust for pH after the nutrients... as Zandor says, the nutrients have a "buffer" effect on the water's pH. So it doesn't make sense to correct for pH, mix nutes, then re-pH the thing.

Hope this helps dude.

Best,
