bump man lights are off now. now i cant do nothing till after work tomorrow. hopefully they will be ok till about 630 tommorow

Got pics? Probably either your nutes or your res. temp. If its root rot good luck. If I were you I would go to your local hydro store and get some MycoMadness A.S.A.P or some sort of beneficial bacteria. That should do a good job eating the dead root tissue and producing those pearly white strings of goodness.

thx capt. i appreciate the help

If you are using hydro use H2o2 (peroxide) and make sure you have some kind of root stuff to help heal (rhizotonic). Soil i would try beneficials in.

If your using organic nutes, do not use hydrogen peroxide..it'll kill em.

thank you also n1knightmare and closetgrowth good to know about the peroxide and organics
