nitrogen slow release in soil with peat moss and perlite in it?

i'm using sta-green flower and vegetable potting soil with peat moss, perlite, and plant food that lists .05% nitrogen slow release that lasts 9 months? I know you're not supposed to feed them until they get bigger so will the nitrogen fuck up my plants? One of the sprouts just came out to the first 2 round leaves but they're leaning over. I hope thats from me not planting the seed deep enough instead of it being from the nitrogen in the soil which in that situation id have to switch the soil and pray. By the way, the plants are in starter cups and I plan on tplant them outside in a few weeks. The weathers been 75-80 since I planted them yesterday and I watered them once. It's humid where I live 60-85% and the soils moist. Any tips or advice would be well considered from those who have done this before.

just wait a few weeks before you introduce nutes, they will go fine for atleast 3 weeks with no added nutes, and if you are really worried about ur plant leaning, it is either stretching (due to poor light), but prop it up with a tooth pick
