Nute question.

So I picked up some superthrive and some pure blend pro. Is it ok to use together?

So ive never used superthrive but ive heard mixed reviews about it. Some people say its a bunch of crap but ive never heard of people having problems mixing it with other nutes...

I mix in superthrive with my nutes and have never had a problem

ST is synthetic growth hormones and vitamins, not a fertilizer but a non-plant food additive. It's okay to use in combination with fertilizers. Personally wouldn't use ST throughout growth, just for clones.
