I think both are good, but there are differences. Foxfarm is chemical and organic. Floralex is a chemist. In the end, cannabis doesn't care if it's one or the other. But I always recommend using an EC meter.
In the past Foxfarm had a brand called Rasta. They are now called Cultivation Nation Micro Grow and Bloom.
Gringo Rasta Lickety Split
Gringo Rasta Super Sonic
Gringo Rasta Funky Broadway
They are chemical fertilizers, with the same formula as GH Flora Gro, Micro and Bloom. But I can't find them...
