aeroponic help

:confused: been growing for awhile now,but i am trying a new set up.Have 25 site (5 tubes 5 per tube) aeroponic system i made.I am having trouble with what seems like damp off (tan slimmy weak roots) and black mold in the tubes.Clones have been flower for 2 weeks (did real well first 5 days)now they are in bad shape.Growth has stopped completely.They can still be saved i believe if i can get the problem takin care of.
I m using: GH flora series and a little superthrive
1000w HPS
running the pump 30 on 15 off
started using HYDROGUARD 2 days ago seems to be helping a little (2t per gal)

any suggestions wld be very helpfull, and how often should i be running the pump?

Were they in dirt before you moved them into hydro?

Hydroguard works great, if you are willing to spend the money go hygrozyme . . . cost more but works wonders on root rot

ill check out the hydrozyme thnx for the info on that!
they were in my aeroponic cloner, from there to the flower tray for 10 days ,and then into the aeroponic system

could be trouble for your whole system.... forever and ever ... bad shit can get into your plastics that bleach can't even get rid of....

Then you have fungal mold or fungal rot. It happends sometime you need to do a full cleaning of your system with Bleach.

If they are not dead yet try some H²O² to clean the roots and give them a shot. Mold is bad and will kill you so be very careful.
