All right so you've now seen that there is an interaction between your nutrients and some combination of water/dissolved gases in your res.
If there's a hydro shop nearby, take a tapwater sample to them to see what your EC is- you need to figure out if you can even use your tap water with ANY nutrients. And you DO need nutrients!

The 4 little ones are I think almost 2 weeks and they are doing fine but i did move them into the res. theother night when I cleaned it out.
So they have had no nutes!
