Thank's Pay It Forward.

So you really don't use a low percentage like i've read before.
I watched the Urban Grower on his site where he visit's medical marijuana
grow room's and they all used advanced nutrient's with the company's
nutrient calculator and they also went by what the calculator said.

800ppm week 1 and went up week to week till they reached a certain
ppm.The grower's were getting 2+ pound's per 1000 watt light.

They were getting bud's as big as a person's neck.You should check the urban
grower's sight out they show some hella bud's on there. http://www.urbangrower.com

My plant's are about 6-8 in tall with around 4 0r 5 node's and i have been using 400ppm but i am getting light patching on leave's (two tone)and dark vein's.I think my ph is fluctuating to much causing a little lockout.

I wish i could show picture's but i have no digital camera,you might have exerienced this before.
