Flushing:
---------------------------------
I have a couple questions since I am coming upon it...I purchased florakleen from GH at the beginning of my grow. Since, this is still my first hydro grow...When is it a good time to start flushing tray #1? How much of this crap should I use...and when flushing should I continue using cal mag? Honestly, I get no really great answers on this when I ask...I guess it is a subjective question (depends on the grower). But, hey any ideas would be awesome.

One Major wrench to throw in:
-------------------------------------------
Also, There is an issue that I have neglected to speak about this entire time. One of the plants in Tray #1 is just now starting to bud...its gotten its crazy veg going on where the massive colas would form...and there are flowers forming all over the plant. Not a hermie...I swear.

Why the hell would this plant take so long to develop...and since this is in the same ebb and flow tray, how the fuck am I going to flush? Should I just clone the shit out of this plant? I dunno what to do with it...it is big bushy and beefy...it would be a shame to kill her for the sake of the other buds....

I have also been contemplating harvesting the tops and letting the bottoms continue to get more growth out of them...thus, letting this one plant play catch up. (perhaps I need to let this whole thing go to 10 weeks?) Suggestions would be great!
