m0useanswered grow question 1y ago If you follow their directions they say to use 20ml per 10L or 2ml per 1L in week 1
If bio buzz all mix does not have any nutrients in it, then it would be ok to use a bit even a half dose. 1ml/1L If it does have something in it then its not likely needed. I have not used biobizz light mix before and forget what its formulation is. Their website is not 100% forthcoming of this information. I do remember it is peat based and not soil. this green power product is good with soil based grows and not recommended with anything that used pumps.
Just note that the Green power 5-1 has low to no P in its formula and attaches a bit of soft rock phosphate powder to the package for this. Mixing a bit of that into the medium will help. it does not go into the water. soft rock phosphate is slow release and is not triple super phosphate that is quick and immediately available.
