Hello,

I hope you can help. Heres the specs

Plant : White Berry(middle right) g13 Power Skunk(the rest)

Res Temp : 65F

Water: Tap 200ppm

PH : 5.7-5.8

Nutes : GH 15:5:7 127ppm

Growing Medium : Aeroponics

Ages: (about) 2 weeks

Last night I tryed a new cooling methed. I pumped cold tap water through a CPU water cooling radiator. It's made of copper and aluminum. The res temp was at 75F, I turned it on for 1 hour come back and was like damn! The temp was 58F Works to good!

Maybe I shocked the plants? Maybe stressed? Roots look GTREAT

(time lapse sucks, but it cool, it you look, you can see it growing. Its a good way to track plants progress. sry for the gaps in video,batterys keep dying.)

Maybe Magnesium deficiency? 1 tsp epson salt per gallon?

Or maybe the Nitrogon is locking out the Mg?

15:5:7 I think the N is to high. but in the time lapse video you can see the growth in just 2 days. ummm Help

P.S I was having a ph fluxuating problem from the tap water buffers. I get it to PH 5.2 And a day later its at 6.3 or so. I bring it down to 5.2 again the next day its at 6.1 And then I bring it down to 5.7 and it holds there for the most part. the next day it'll go up 0.1 ph And I add PH down to 5.7
