Nitrozyme

Hi I promise I have searched for threads relating to this but haven’t yet come up with anything

My plants are 3 weeks into veg, I mixed 1ml of nitrozyme into 250ml of water and sprayed about half of it on to about 10 plants and when I say in ~6 hours I’ve seen visable growth on about 7 plants and I mean monster growth for 6 hours lol

Anyhow I can’t seem to find how often to spray them? Once a day? Once a week lol
