Hey alfonso2002,

If that's the case, happened with the start of nutes, it is very possible that you hurt the roots with too much nutrient.

Aeroponics only requires abt 40% of the nutes mfg's recomended amount. And if at all possible I would start out at abt 20% concentration. ie: use the amount of nutrient you would for 1 gallon of water, but add 5 gallons of water instead.

Just looked over your trouble form again, and realized you have a TDS meter. 900PPM is too high, not the worst I've seen someone try but it's too high.
Probably abt 600PPM is the most you'll ever need and a starting point would be 300-400PPM.

The only other thing I noticed was your PH is just a little hi, shoot for 5.5 or so.

Good luck, keep us posted.:thumbsup:
