I'm wondering if anyone here has used the following AN products In dwc system? Iguana juice, tarantula and piranha. I am currently using these three organic nutes in my dwc and i am getting brown roots... Not root rot, I don't think anyway..... The roots are not smelly just brownish and there is a little bit of foam on top of res. Most of the discoloration is between the top of the res and the bottom of my net pots. I'm hoping the brown roots are just from the organics. Also it seems that not all the tarantula wants to disolve, Lea ing a black sandy deposit in the bottom of res. There is no light leaking into res and the roots under water are alot whiter than the roots in the air..... Any one else have any dwc experiance with these products?
