Hey jack,thanks for the input. Ur rite Bushmaster is an enhancer and I used it as such, but have never experienced such drastic bendng of the leaves .
I spoke to the people at Bushmaster today and they explained what I did wrong with this particular strain. I'll post some pic's in the near future..Anyway my problem was that I got "ppm happy" and kept on with elevated ppm levels.
Firstly, use a kelp spray from the beginning of veg, not just the week before going into flowering. For aeroponic systems it is strongly advised that you use only water with no nutrients for three days. Also use a lower application rate 1½ml - 2½ml per gallon (depending on variety). Aeroponic systems deliver nutrients/additives directly to the root system continuously, thus absorption is high through the root system. Also make sure that the water temperature isn't to low (below 70°F).

Personally, I wouldn't apply Bushmaster through the root system in aeroponic systems. It is suggested rather use it as a foliar spray at 1ml per gallon. If Bushmaster is to harsh on your sensitive plants then foliar application is the way to go, the leaves are tougher than the roots :thumbsup:
