Drooping leaves pics.....

any ideas what the problem is if any, i was thinking either heat stress or lack of oxy?....
temps during light vary from about 80f to 90f. dark temps are around 69f to 72. I was think since im using a bubble system ,there isnt enough air in the water is this a sign of that? any help would be great.

temp too high...don't go over 78 in the grow room...are you feeding them nutes?? not sure about the aeroponic question, i've never tried that

i dont see a problem

going over 78 isn't bad i know people that are over 90 and fine. 95 is the limit however. mine is usually at 88F and is fine

excellent good relief any other opinions?

i know people who go in the 90's but have co2 going

im actually about to go and fill my tank as soon as i can locate a regulator any ideas on where to locate a cheap one? im going to be using a 20oz tank

yeah i know people do grow up in the 90s but.. id still aim for 75 degrees if you can. your plants really dont look to unhealthy, i wouldnt worry
