Thanks for the info Flo got it heading my way now 
Do you see fluctuations in your reservoir when checking PPM / PH? It seems if I put the meter over the water with more bubbles I get drastically different reading than the rest of the reservoir. This fluctuation is making me concerned I have a reservoir change Sunday... onto full strength flower nutes, I'm going to move AK back under bulb and the WW back to more or less under the end of the bulb and more of the reflector.

You mean when you stick your probe straight into the res with the air stones on and water bubbling???? If so I noticed the same thing I just dip a clean plastic solo cup in my res and check that way ...

I avoid the bubbles too !
Never thought to mention it though, my bad.
Or do like BH, and use a seperate cup.
I do see flucts, but that depends on if my plants ate a little or a lot.
Sometimes there will be no flucts in ph or ppm, just the water level.
Mostly stable like I said.
I add ONLY water back daily, then bump the nutes back up if they fall by more than 100 - 150 points from their previous max level.

Good idea. I'll try that so I get a more accurate reading

yeah dude I have a 250 dollar Hanna Grow Check Combo and its a really good meter and when I put it inside the res it did the exact same thing with the PPM. Just dip a clean plastic cup half way or less and get your reading that way ..So its definitely not your meter because even a top of the line one will do the same ...
