Ive used biobizz for 20 years, and like its results. It is however, not the same product, i started using all those years ago.
Definitely better results, with softer water. Especially when it comes to availability and uptake of micronutrients.
I also used biobizz's cal/mag product,which helped very much. Worked much better than other products ive tried to use with the grow and bloom.
Not sure if alg a mic made any difference. But acti veras affect, was noticeable. It made the plants prey when sprayed.
I've never really liked top max. But as its the bulk of the micronutrients, I've started to use it again.
