roots

Ok so my plants are about a month old was about to put them into flower today and noticed the roots are starting to turn a little brown in some spots. Could this be root eot or just them drying out and dieing. Im using an ebb and flow system. Please help before i go to flower.

Is the water temperature being kept below 69F?

i just realized my temps in my dwc setup are getting rather high also and roots are starting to turn yellowish and the ph is decreasing...pretty sure the water temps are causing root rot. the temps of the water were at 69F-72F a few days ago and its getting pretty hot outside now making my room temps close to 80 all the time and water temps are getting up to 75-79F wayy too warm. idk how im going to cool them yet

Some people put frozen bottles of water in their rez to help lower temperature.

thats what i was thinking of trying...i did manage to throw the bucket over a duct for my central air to cool it back down. today they got up to 78F-79F and so far after an hr its dropped back to 73F since its been on the duct.. hopefully if i turn the room temps down to get them at about 72-75 the water will stay a few degrees less than that... cant wait to see the power bill for this lol.. i need an energy efficient ac unit just for the room so i dont have to crank the central air on when the lights are out.

Yea i am having a hard time keeping my room cool have it in its own room it is 2x2ten keeping the front unzipped while the light is on running a led and a 150cfm fan dont know why i cant get it below 80and the humidity is down since i put.it in the tent. Cant afford to run another inline fan. Im about to get a small room humidifier. To try and get some humidity up. The tent is becoming more problems then good.

what if i were to throw the air pump in the ac duct so its would be pushing cold air into the bubble buckets instead of room temp air into the buckets? would that be enough to change anything?
