Fresh air intake from outside is not possible. The best I can do is have cross ventilation in my house which provides fresh air in my house at all times. However, it's 27 degrees outside and falling so the windows are closed for now LOL. The roots look healthy to me according to pictures I've seen of healthy roots. I'll post some pics here in a moment. Thanks for your help. The plants are looking better though I think. I'll post some pics here shortly.with the lights that low and plants that young any foliar spray might burn the fan leaves.Is the water warm or real warm.. take a small water bottle or two remove some water and squeeze the air out so it can expand and put it in the freezer. then drop it in your rez tank during the middle of your light cycle or hotest part of the day in your area. it will drop the temps cheap if the water is too warm.I would really reccomend some fresh intake air from outside if at all possible.10 feet of 4" dryer hose should be less than 20 bucks at any home repair store. you could even place something frozen in front of the air intake to cool the air cheap but it will raise your Humidity.You can also get dry ice at most supermarkets but its not cheap and wont last long.water with a low ppm is good so thats not the problem. you said the rez looks like a blondes head in water. are your roots a blond/rust color or brownish stained or closer to white.dark roots would tell me nute burn.if the res is full of roots make sure nothing is clogged up.white roots are good. IMHO with the lights higher and the ph around 6 and cool fresh air intake that should Help lots but i am not there.double check everything.you said your ppms were down from 760.thats high. I would give them a light water only flush,then a rez change and an hour light break will let those temps drop on that metal.
