Leaves are drooping. Why?

My leaves are drooping as you can see from the picture. There are 8 plants and only 2 are like this. Why? Please help!

I will tell you that the Ph is at 6.0 and the termp is high at 92 degrees. But why only 2?

I've done waterfarms, and for me it was root rot , and root aphids that led to this.

Try plain ol tap water for a few days... they might recover, but ts not likely

waterfarms don't do real well in hot rooms. I've learned to keep the water level a little lower, run the nutes real lite, and use dutchmaster Zone to help fight root rot.

i was just gunna mention...look at your medium? looks like algea, could also be uncleaned up fallen leaves? no...algea dude.

Thanks for all your comments. This really does help me. I do have algea and i'm sure its because of the heat and this affected my roots.

...light shinning onto your hydro medium will cause the fungi also.

Those have to be the worst looking plants I've seen on this site. Even the non droopy ones look stretched and very slim stemmed. I don't think there's a chance of those droopy ones recovering.. Now that I've sounded like a complete and total asshole .........

I wish you the best of luck and while I'm no expert I think that if you provided us with some more info like a picture of the overall grow room (to see lights, vent, overall set up), nutes you're using, how much water, and as gobskii said, the medium it would be easier to make suggestions. Conditions clearly aren't optimal and I don't think this droopiness is from the typical over watering but not sure.

How big is that Rockwool cube that is in the hydroton? Do NOT use a big (more then a starter plug size) Rockwool cube, it holds far to much water for the type of system you are growing in. Waterfarms recirculate constantly, you need to use a medium that allows oxygen to get to the roots, like hydroton or perlite etc. 92f is not only your air temp brother, but also your water temp, and that my friend is completely outrageous. Your water temps should not exceed 68-70(max) without hydrogen peroxide added, with h2o2 you might get away with a bit higher water temps, maybe up to 75-76f, but then you are just shit out of luck here. Soil would be a better option if you can not control your water temps i.e. chiller+main reservoir. The plants are stretched as hell, so there are most likely some lighting issues as well.
If you give us some more info regarding your environment etc. we will try to get you closer to the promised land brother

BTW, this grow is done
They will not recover, you ned to dial your grow room in!
