Well I'm not sure how far along you are with your grow, but if it's really small I wouldn't even give it any nutrients. Once it's got a few branches or at least 2-3 weeks old, you can start it off with 1/4th and watch it. If it didn't look like it did anything, you did good, because it's still alive. lol. And after a few waterings, you just increase it by a tiny bit.

I originally read your post thinking you are giving them Miracle Grow nutrients. If so, then as long as your staying at your proper NKP values and don't do anything drastic, your fine. If your using their soil for seed starting, that's okay too, but if it soil has nutrients (it will say "feeds for 3 months") then you should flush (rinse) the soil first. The their organic is the exception, some bags will say "feeds for 2 months" but its okay. I never hear about their Organic mix burning any plants.
