Snow storm ultra question

I've been considering giving this to my plants to increase trichome production, but I can't find anything online about if you can use it outdoors or not. Does anyone know if it works when growing outdoors? And is it safe to give to my plants because I'm already giving them maxsea bloom once a week and I'm just about to start giving them humboldt nutrients ginormous with the maxsea as a booster, I don't want them to get nute burn or anything worse.

indoors/outdoors
You shouldn't have any problems, just follow the directions.
You can foliar the snow storm if you don't wanna mix it with your nutrients.
or you can mix it with a watering.
I was using it once a week mixed with my nutrients.
