Would you mind filling us in on your medium? It looks like your pots are probably bottom-less, and go into soil? Do you dig out holes and fill with premium soil, or is it natural? What nutrients do you feed them, and do you have a picture of the tanks?
A few of my buddies in S. OR (where I live) are doing big vats w/ air pumps and nutes, in huge "brews"... are you running a similar system?
Any info is appreciated.
