Let's say I'm about two weeks from the sprout. My "GIRLS" have about 8-10 leaves on themselves and are looking very healthy. I am using a 400 mh for now on a 18/6 cycle.

When should I introduce the nutrients? I am using foxfarm organic soil and plan on using the foxfarm nutes.

From my reading and understanding, you can start your plants on nutes as early as 4 weeks from sprout (germination).

Good luck!!!

Best thing to do is let the plant tell you, when the leaves start to yellow slightly then the plant is telling you it needs more nutes as long as it looks healthy and green it only needs what you have been giving it so far, if the tips and margins start to burn then you know your hitting it too hard.

Best of luck bro. ~

you can use those as early as 4 weeks, at 1/4 nute strength. Remember though, if your leaf tips on the top and middle turn yellow/white, even a little bit you need to keep the nutes where they are for at least 2 weeks. if you start to get yellowing near the bottom of your plant, up the nutes to 1/2, depending on the type of yellowing.
