I've been looking for a calcium additive and after your post I went onto the Growth Technology site. I didn't know they did one and I couldn't find it on there at all. But I also couldn't find chilli focus and I know they sell that. The have a link to their newsletter and the last one is from 2007 Guess they sort of neglect the site.
They are just down the road from me so I'll go in and ask.
