Re: fertilisers LIST plus mixing

thanks for the advice - these ferts are sold as water soluble - and you're
right, there other analysis available.

I don't use much chemical/artificial fert anyway, but i want to add the K to
boost the development of the set fruits - i don't normally start using for
two or three weeks at least yet.

I will probably go for the 9 - 9 - 27 and try and get hold of some calcium
as suggested.

Chris
