thats not the stuff i use its actually called flora nova its a single bottle for veg and asingle bottle for bloom. it should be about $60 per bottle which isnt that much cheaper but its a significantly smaller amount u use each change so it works out cheaper that way.
it does actually have considerable salt build up but i always run a flush through each weekend with florakleen so i have never had a problem.
there is no harm in giving it a go but i know u love your cyco so dont change on my behalf. different things work for different people. thats one of the main things i have noticed on these forums there is a thousand different ways to do things and for some reason one way that works for one person just doesnt work for another i cant explain it but it seems like that is the case.
also i just popped into my mates store so he could fix me up with another bottle. he gave me a free bottle of bloom a and b.
he also said its a case of not enough preservatives in the cyco nutes but he also said that he believes they have fixed the problem so it shouldnt happen again.
