Why are my peppers barely growing?

I planted these seeds over 4 weeks ago, they sprouted on average about a week after and this is their progress so far. It seems like very little progress so far. They don’t seem to be dead they are still growing just very slow (the three tall ones sprouted first before the light was in place so that’s why they are leggy)
