Good to know, I have been having some burning issues with the PurpleMAXX, that and I didn't cut down on the nutrients like it stated, big mistake. Could definently add a few days to my harvest. Of course I think the issue may also be that I haven't flushed the soil... since I can't, hate that I had to plant them in a single tub, imposable to flush without drowning the poor things, oh well.......
