Gelato 41 & White Zerbert DWC

Rough week on this one. On top of the spider mites, I found out there was a root ball or mildew or something that got stuck in my water chiller. My pump wasn't able to flush it out and my water flow almost stopped completely. I bought a stronger pump, shot that crap out of it, and let it run with bleach solution overnight to sterilize it. My res shot up to 78 and root rot took hold very quickly. Once I saw it, I immediately pulled the plants and got them soaking in a h202 solution with no nutes for about 3 days. Once added back to the nutes, I removed the non sterile nutes and added about 0.4 ml of bleach to the 7 gallon reservoir. These plants were on their way out in a hurry, hopefully they can pull through
