My setup:
2 - 600watt HPS
AC unit keeps room below 75 degrees
Chiller that keeps my temps no higher than 73 at worst but normally about 70.
Dutchmaster Gold series nutes
R/O water
PH is swings between 6.0 and 5.5
PPM has been from 800 building up to 1900 over a 2 week period.
I use a little less than the max amount of DM "Zone" and DM "Silica"
I'm growing Blue Rhino, Grape Krush x Blueberry and White Widow.
So here's the deal. I've been a soil grower for a few years with excellent success. I decided to go Aeroponics and build a system. It consists of 10 - 5gal buckets with a feed and return. The pump sits in the res and sends water/nutes to the manifold which sends pressurized solution to each bucket. In each bucket is a smaller manifold with 4 jets attached. then the solution flows out the return hoses into the res.
OK
So, my first grow was relatively successful but I think I pruned them too hard which caused some slow growth. But it turned out marginally better (albeit WAY quicker) than the same number of plants in soil.
My second grow was a complete disaster. The veg nutes had gone bad somehow and it basically poisoned the root system and killed all but 2 plants. Those 2 were stunted and produced about 4 ounces total.
This is my third grow and I'm having issues with slow growth and signs that look like deficiency.
Everything seems to me to be perfect but the plants are not responding well.
Only one is (a WW) is just now starting to pick up it's growth but the other 9 are showing signs of deficiency and are growing very slowly. WTF?
Last night I added a 3/4 dose of Hygrozyme.
These picks were taken on 6/17/2009
I'll take new ones today at lights out.
