I would be wary of going from soil/soilless into hydro. I have seen that kill several crops for friends. I would try to keep the hydro system sterile, and soilless mediums can often harbor plant pathogens that are kept in check by beneficials, but things can get out of control pretty quick in hydro.

That would lead to root rot, which would lead to physical symptoms like you are seeing there.

If your roots are white and fuzzy then no problem, brown or slimy then you have a problem. imp:
KaptainKron Reviewed by KaptainKron on . Brown spots, yellowing These girls have been in a mix of sphagnum moss and perlite and being fed Fox Farm's Grow Big for hydroponics. They have now been in a aeroponic system for a day. Perhaps now they are in the system they will recover but I'm curious to see what you guys think. They are about a month old now. This is my first grow so its been bumpy and they haven't had the best conditions concerning lighting and nutes. Rating: 5
