I just had six jalapeno plants push through the soil the other day in plastic cups in Miracle Grow seed starting potting mix and the stems look really long. I put them in the window sill and they all leaned toward the window. Did yours grow a long stem, I'm wondering if I need to do something about that or if that's normal. This is my first go at planting anything and I don't want to lose the little fellas...any advice?
