I started with the floraseries more than 20yrs ago. I've also tried many many other base nutes that have come out since. I use the Maxi because it's cheaper than most and works just as good as most
Just a couple pointers on the nute soup you brew:
If using the floraseries and you need more Ca bump up the micro. Being that you're in pure coco and rocking the 3part, I like heads(h3ad)modified lucas formula best. 6/9, micro/bloom and a little epsom salt. No need to buy calmag
Floralicious plus sounds like it would be hella beneficial, but I have not come to the conclusion that it is. And I've experimented with it allot.
Liquid koolbloom is a joke, along with AN's big bud.
Powder koolbloom can do things like make buds harder, but I find it to fuck with my yields. I don't use it anylonger and i feel good about it.
Carboload is totally unnecessary
