I started using Hypochlorous acid since the AN guide recommended stopping use of the beneficials, I noticed very interesting things in the roots. Very fine angel hairs growing thick in the roots. I'm wondering if it do that before because it didn't need them because the beni's and the enzymes I use made it more efficient and now they're starving, or were the beni's and enzymes holding it back, and now that I'm not running them, it's flourishing? Food for thought.
I've never had an issue with them in the last 10 years that I've been using their lights. I've had 3 different models too, are you sure you didn't buy something used or a knock off?
