Thank you so much for answering.Activera Is aminoacids and basically a stimulant based on aloe vera by biobizz itself.So the main 2 parts of the biobizz nutes are: Grow for vegging, and Bloom for flowering.
I would use that as your starting blocks instead of trying to use additionals in replacement of the 2 main nutes.
Yes: you can can use fish mix (it's got N in it which the plant likes for vegging) - not sure what activera is ... sounds like a healthy yoghurt drink ... which would possibly also be okay for your plants ... but i wouldnt test that myself.
Hope this helps

About the main blocks,since I am doing a FPJ and want to feed organically grass grown near my house for vegetative stage I wanted to skip the vegetative main nutrient.Would you suggest It?
