First advice I would give you is you should not plant all of those seedling in one container they should all be in separate pots. your seedlings are stretching to high put the light closer to the tops of the plants. Most important of all is to read their is tons of info on this site along with some very knowledgeable people willing to help if you take the time to search what you are trying to find out before posting something that has been answered. I hope this helps and good luck.
