When should I harvest?

I figured that the more plants in there, the better use the nutes would be put to, and I might have to fill the res more often, but at least my one flowering plant isnt sitting in stagnant over nuted water for so long

That's a logical conclusion to reach but there are a couple other factors.
The ratio of plant/root mass to available nute solution determines how quickly your res conditions will change over time. So there is a point where you have too much plant for too little water.
When in doubt, add an airstone to prevent stagnation, and keep a regular schedule of changing the reservoir out entirely for a fresh solution.

hmmmm, thanks stinky, i didnt think about that. I do have 2 12" airstones in there. btw, the plant is doing a lot better, and theres a lil more growth starting.

Also, I completely change my res with a full cleanout every week or so. I don't top off the water unless i test my ph and tds and know it wont be 2 big a strain on the plants
