I have a chiller on my res set to 68f.
I'm going to try mixing the mini cubes with some rice hulls.

I'm gonna try putting the pots into a root tapper bag to help insulate and reflect the light from the pot like this.

I can only offer my observations, I don't know why this works but it does for me. I made my own simple hydroponic setup from stuff I bought from the hardware store because I'm growing in a bedroom in my house and any other kind of soil or medium is too messy and hard to deal with.
I cut my own rockwool blocks from slabs to fit my pots. The cuts are rooted in small rockwool cubes then transplanted to the rockwool in the pots for veg. There is nothing else in my pots no clay or anything just the rockwool.
The pump runs 24/7 so the roots are constantly wet even when the light is off and I don't have the problems described here. I'll clarify this and say the roots are always wet but not submerged in water, it's constantly draining. They are also exposed to air. The res also has 2 air pumps so the nutrients contain oxygen as well. The rockwool in the pots stays relatively dry not waterlogged anyway.
I'm certainly not trying to say I'm right just that this has worked consistently for me. Better than the systems I've bought from hydroponics shops anyway.

I just switched from rock wool myself because of these issues. I no that guys have great results with it so there is no denying that. I personally just couldn’t figure it out. Always had moisture problems so I don’t even root my cuts in it anymore. Anyways good luck brother hope you get it straightened out

I always water with water that's less than 76 degrees. Preferably 70-72 degrees. Easiest possible way to chill your res is to grab 2 1 gallon jugs and freeze them overnight. Put it in 30 minutes before you start feeding. Should be cool enough feed.

I use an enzymatic cleanser called Z7 and haven't had root rot in years. Half a ml per gallon and you're set.

I love Rockwool 1" rooting cubes WELL rooted transfer to the large 4"cubes and onto NFT hydroponics. if your ph is on point and you root them well then there is nothing that compares. fail the 1st stage is where most have problems that continue.

When I ran hydro DWC, I would keep the water temp low and add hygrozyme. Never saw any root rot...
