Im thinking it might be too much water. Maybe the plant just needs a change of scenery or maybe just change the soil? A healthy seedling should just stop like that. When it happens to me.. I just take a good look at the condition of the plant. When it happened to me... it was getting too much...
I have orderd from Peppermania many times. I always get what i order and you cant beat the prices and shipping is fast. I had very good luck with my seeds. Its also fun when they give you the mystery seeds, its a fun little bonus. Fast... Cheap..good quality ... good selection.
Im happy that i found this site. I love growing different kinds of pepper and giving them to family and friends. Its fun showing them how many kinds of peppers are out there. Hope to learn a lot from the community about peppers. I should be putting up my list of pepper plants soon.
