Its a good Idea to have an airstone in the res, (if you dont) especially if roots are in it. Also this may be one of your problems, 2 weeks is too long between res changes. I was doing 10 days, now I do 7, and they are a lot healthier than previous grows. h
I always do the PH after the nutes, cause my nutes affect my Ph up to a whole point. And ya I would get some kind of cooler in there. I keep mine between 65-70. Like Steve said, "the cooler it is, the more oxygen the water can hold". h
What Ph is your water your using? Most tap and store water starts at 7.0. My nutes usually drop it a point. What are your Ec's?
Temps can have a major affect, I dont let them get above 70. I have 2 two ltr bottles full of water and during the summer, I keep 1 in the res and 1 in the freezer...
You shouldnt have to add enough PH up to make too much of a difference. In fact the only time you should have to add it, is in your initial mix. After that the plants should keep it up if they are feeding properly.
I always Mix my nutes first, then fill my res, and then adjust the PH to 5.5ish...

Well I have a pretty nice digital with 10x. But just like everything else in life, its actually 4x optical and 6x digital, and when you try to use any digital zoom, it totally screws the picture quality. I think the only ones that give the pics...

Re: Flower Report G13 Haze GLH 180W
Thanks, and may I say you have done an excellent job making that plant give you all she can. The lights are Lighthouse Blackstar 2x240w w/3w Cree LEDs. I couldn't afford the real expensive lights. (I wish) I heard Cree makes an excellent product, so I threw...
re: 480W & 720W Grow LED Hydro - Land Of Clovers
I agree, I know you guys are experimenting with new stuff, but just reading about it is stressing me out. I cant imagine how the plants are taking it. I even noticed on mine, the Rock Wool seemed to have an affect on the PH. I quit using it...
Re: Flower Report G13 Haze GLH 180W
Sure here is a link to my photo gallery. The ones marked "Close Ups" are most recent (Sun) @ what I was calling 20 days flower. You'll notice the leaves on mine are even more burnt looking than yours, especially under the LEDs. Ive had my ECs kinda high (2.0)...
