Root rot?!

My 2000 is finishing one at the moment, iam gonna start using it in 2 weeks. And the brown washes right off the roots, I did add some ro and calmag water to bring down my ppm, and it washed the brown off real easy.

Your plants look fine. The roots look stained, but not mushy so I don't think it's rot. I always use hydroguard anyway so good call there. When in doubt, change the res. Especially if you're almost a week or more since the last res change. With the number of plants you have, I think you should set up your TSW 2000 if you haven't already. 24-26".

General hydroponics. Its a medium brown res. I was hoping it may be just stained. The plants seem some what healthy to me. A little dropping, but that got better. And just that one brown spot.

Gmslave, thank you. Ive been worrying about raising it to much. I noticed that the ppm is lower this morning by 20 ppm. I will top it of with ro and cal mag. And get it back down to 600 to 650. Again thanks.

Sorry. The roots look stained. Are you using dark coloured nutes. Should be no rotten at those temps.

A little info on your next question. When you add your own comment, it looks to others that someone has already answered your question. So many skip by when the see 1 response. Cheers

Your nute level is to high for this stage. Week 1, 400ppm 0.8 ec Week2 500ppm 1.0 ec Week 3 600 ppm 1.2ec Week 4 700 ppm 1.4 ec Week 5 800 ppm 1.6ec Stop there unless plants need. Cheers

Iam switching to hydroguard. It arrives tomorrow. Pictures are on my diarie, week 3.
