Is this good for flowering?

Yeh,just dont use too much ...

Yeah that a bloom type nute for sure. Its really hot so make sure you only use 1/2 strength at most....I would use a little less for starters. Definately make sure you do a full 2 week flush before harvesting. I bet that stuff might taste a bit nasty if not flushed out properly.

Should i use that, or stick to MG 15-30-15??
