Thanks everybody for ur input! Lastnight I soaked all my bloomers in warm water to drown out a bunch of fungus gnats while I cleaned the tray, reservoir, pump and bubblers. What a mess!!! Never again will I get clones from a dispensary!!! Tons of Gnats...I understand I can't kill them all by flushing but at least there are a lot less of them. Refilled reservoir w/ ~8gal filtered water 7.6pH 210ppm. The nutrients I added were 6tsp GH/FN Bloom, 4tsp Floralicious Bloom and 2tsp liqiud KB, bringing the solution to 6.4pH and 780ppm. I checked my pH at lights on and pH is at 6.9, less then 24hrs after refill. I also installed my CO2 emitter, it's on a controller, like I needed to add anything more to the equation/problem!?!

@tinytoon, I'm honored you're droppin by to lend a hand.
Veg.-GH/FN Grow:7-4-10 and Floralicious Grow:1-0.7-0.6
Bloom GH/FN Bloom:4-8-7, Floralicious Bloom:1-1-1, Liquid Koolbloom:0-10-10 and I have but have not used yet Dry Koolbloom:2-45-28. Also, I use EarthJuice's Natural up/down(more down then up).

@polish, Thanks for the info. I agree with you that there's a nitrogen deficency and looking at the plants tonight I'm thinking they're deficent in all the primary elements. Maybe from the soak? But I just bumped them up from 720ppm to 1250ppm, I also added 1tsp of GH grow form 3part GH. I'm not sure if I want to up the pump intervals or the ppm? Root growth is good and healthy so I know they're not drying out. I don't want to drown them, in the containers I have corners of rock wool cubes in layers. I fill the containers in this order(I use a 3"net pot for scoop) 2scoops hydroton, 4 corners of rock wool, 2scoops hydroton, 4 corners RW , 2scoops hydroton, insert clone in 3" net pot and fill around pot w/ hydroton. I feel the rock wool is keeping the plants from drying out, IMO. Going up to 1500ppm sounds kinda high, but you never know til you try, right?!

@tikiroom: You bring up some good points! No, I'm not going over 1350ppm for right now and again, no, I didn't presoak my hydroton......and that makes a whole lot of sense!!! I will, from now on, presoak my hydroton! I don't know if you've ever experienced this, but I notice I get this white stuff floating around in the water after adding pH down and letting it sit. Any ideas?

@D.No$: Thanks for pointing me in a good direction.

I will have pictures up here and my grow log tomorrow. Check out my grow it's Nirvana AK48 seed to weed!! I think my problems are coming from this rising pH dilema. I've read that you dont want big fluctuations in ph over short periods of time. What's worse leaving pH at 6.9 or dropping to 5.8-6.0 everyday from 6.9? To get that drop I use about 3/8 to 1/2tsp of down for 8gal of solution. I've been changing solution every 5-7 days adding about 3/4 gal filtered water everyday for 12 plants. Again thank you every one who have stopped by with your words of wisdom and experience!
