Found Some Grow Nutes

hey guys, i found a jar of grow nutes and i was wonderin if i should use them or not....jar says the npk is 17*7*18... but that means nothin to me....my plants arent too tall but i havnt given them ANYTHING (but soil & water) so far and one is starting to tell me so....

p.s. im transplanting as we speak.....if it makes any difference

That will work. It's better for vegging than flower but better than nothing for both.

Just mix at half strength.
