First grow

Hey, I have been researching growing, and have gotten many tips from many people, so yesterday I decided to start my first crop, I got some low PH soil, and a couple of agro lights I had my seeds germinated and ready to go so I just planted them and have them sitting in my grow area. Now to my question, once I get to the point where Is hould feed them plant food what do you guys suggest for a mixture? The crop is, 5 "Snow White" 5 "White Widow". I understand that different plants need different attention so I was curious as to what you fellas think.

they come from the same white family, so I don;t think that there will be as much difference as what you think. after you transplant, and one watering after transplanting, use fox farm nutes GROWBIG. start off with 1/4 tsp then move your way up during feedings. if you are having a hard time measuring 1/4 of a tsp, go to like walgreens and get a child medicine dosage meter. get the one in the syringe form w/o the needle. takes all the guess work out of it. further more, what lighting and what is your room temp?

for the 10 plants I have the room temp at 71* and lighting 2 plants per light 75w Agro (plant light) spots. (the ones with reflective backing to concentrate the light) im 18-6 lighting cycle with the plants closed off from natural light.
