What you're describing can be caused by heat stress. Is it getting soft and mushy or dry and crispy? How dry do you let the soil get before watering?

Well I planted it the 23 n watered it that day and wen I looked at it the 25 it sprouted but didn't look healthy..now its looking a little better,,I'm loading a pic up now
