Tons of brown junk in my res

[sexbobomb]

First of all, I want to thank all the responses, it's very much appreciated.

A little update:

After I did that res change when I noticed the brown funk, I mixed in my nutrients and hygrozyme again, to see if it would repeat the problem. It did. I had to do another res change 2 days later (on sunday). So, after that res change, I decided to stop using hygrozyme. Today I checked my res and there's some brown gunk, but hardly any compared to what it was before. I think my problem is the water temp, I checked it and it was like 80 degrees, so I emptied a big bag of ice into it. I don't have a fridge at my place yet, so that's why I was hesitant to be spending $4 on ice every single day, but it looks like I have to do that from now on, until I get a fridge. I'm so frustrated with hydro, I'm like an inch away from just saying screw it and transplanting into soil.

My plants look pretty stressed, the fan leaves are still a little droopy, although they've all been growing rapidly. The biggest one is 15 inches tall already. The runt is still not growing at all though, it's 3 inches tall and the bottom fan leaves are completely yellow and crispy. It literally hasn't grown at all, and it's probably gonna die soon.

well 80 dagrees is 100% your problem!! use the ice till the FF nutes are gone. Them get a inorganic nute brand and use bleach or H202.
BUT your problem is still going to be there!!! a salution would be a chiller thats a lot of $, try moving your res away from the lights or the
room thats causeing the heat. hydros the shit man I went through the same thing and still do from time to time, so dont give up soil has
its issue to and can be a bitch to deal with to. just dont give up!! +rep for the pateince

Thanks man, I will continue to add ice every day until I get a fridge (should be soon).

What do you think of the photos I posted? Every plant seems to have unhealthy-looking leaves, and the little runt is only a few days from death. On the other hand, the big one is almost ready to flower cause it's so damn tall!

the little one not looking good. and the others look better but damaged leave wont heal themself
just wat for new good looking leaves. most of all you need to stop using FOX FARM so you can
use things like h202 at 7ML per gal every three days and once a week bleach at 7drops per gal
and find a way to lower that temp!!

Amen, brother. I haven't had a single res problem since I ditched the Fox Farm and started adding H2O2 to the mix. And my temps run on the high side. A chiller would be prime-time though.
