They were in a 5 gallon bucket but I moved them to a 10 gallon bin 4 (?) days ago. My pH is stable and monitored 24/7 and the PPM is at 1K so I don't think its a deficiency unless its nitrogen, in which case I'm not really concerned. The Pure Blend has a pretty decent amount of N and the GroTek CalMax I use is 1 part N so it should have enough.

The only brown you see in the bucket is from the nutes or possibly the mosquito dunk I put in there to eliminate the possibility of fungus gnats. I hate those things.
