Dutch Master Penetrator

So i purchased some Penetrator to Use along with pest out to control some spider mites on my mothers. This is my first time using it. So i call up my friend who recomended it and toldl him i mixed 60 ml of Penetrator per 1 gallon of water. He kinda freaked out at first and said 60 ml was way to much. He quickly rushed home because he wasnt sure but thought that the Pene he had was at a much smaller ratio. He is in NoCal, me in Socal. He looked at his notes on what he has been using it and it said something like 10 ml per gallon. We then compared our bottles. Mine had all different kinds of language translations on it. His did not. Both were the same size bottles. But the npk numbers on mine were`.006-0-0 and his were .006-.005-0 or something with only a minor difference. He said this is the only penetrator his hydro store ever carried. And the kind i purchased was the only one on the shelf at my hydro store. They were both about the same price.

So what gives. I couldnt find anything else on the boards that mentions two strenghts. Can anyone give more information regarding this, and which product is best to use in which situation. I havent been back to my hydro store to ask them so any help would be appreciated in case they do not know either.

Im not an expert on this by any means (only just starting to wander over to the Hydro section... not gonna start doing it anytime soon, but its an interesting concept), so the only thing I can think of is that his Penetrator was an 'older' brand. Maybe DM updated the labels a little?
Are they both by Dutch Master? I take it that they are.

you might have run into the same thing I did after I bought Iguana Juice...Advanced Nutrients had made it more concentrated to give growers a better value and during the transition there were 2 different strength concentrates on the market.

I use diluted pyrethrum for spider might problems, by the way...goodluck lw
