I like to flush just prior to moving a plant to flower, and then weekly during the flower cycle. I use Advanced products, though like Dutch Pimp, I'm not a fan of feeding too heavy.. I may go as high as 1200 - 1300 ppm during week 5, but that's the absolute top. As far what I flush with, pH'd water and that's it.. At the end of the cycle, I start flushing normally in week 7 and like to continue to flush for 2 weeks.

This method has prevented my from experiencing many growing problems such as lockout and my stuff burns clean.

The pics are at the end of week 7 on an 8 week cycle.

Anyone growing any long flowering sativas? I have some Amnesia Haze seedlings.. I understand they can go up to 15 weeks... Anything I should be worrying about on the long flower cycle?

Peace,

Farmer Rich
