Answer: Congratulations on becoming a seed starter! It's quite addictive. You should only use seed starting mix while your transplants are still in pots indoors. Once the height of the transplant is 3 times the diameter of the pot, then transplant into a pot one size larger. Keep going until you're ready to harden off your plants. Keep them well watered, fertilized lightly with a liquid fertilizer weekly and give them plenty of light under grow lights and they should be fine.
