Seedling stem gone limp

could be alot of things, too much water, not enough water, not enough light and is trying to stretch up to it and is just to weak to support itself. got a picture?

Do you have a fan blowing? When they have a slight breeze it strengthens their stems.

I had this happen a few days ago on a sour diesel seedling the stem bent sideways and was really thin at the bottom all I did is gave it a good water, pack the dirt around the stem at the bottom, and put it about 2-3" away from 26w CFL and in two days it stood strait up and is starting to get out of shock and start growing again, it also got its darker green color back. I also have a fan on low to strengthen the stem alittle.

too much water, i have some seedlings in a small cup that are just coming up. i had misted the soil every day for about a week. now that they have came out, i will not water them for another 5-7 days. the water i had been misting onto the seed, to sprout it, collected into the middle and bottom of the cup, (1)and provides enough for the first week. at the begining of the (2)second week i will water again with quarter strength nutes. saturate the soil to make sure nutes are all in the soil. (3)water 3-5 days afterward with twice as much water as soil volume in pot, to flush it. during the third week, (4)fertilize with 3/4 strength or 100% strength nutes. (5)water 3-5 days afterwards with half as much water as soil volume in pot, not to flush it, some fertilizer will stay in the soil to provide for another week. repeat steps 4 and 5 how ever long you veg, make sure you finish 5 befor you flower.

need pics too many different options with out seeing it.

I had that happen to all of my seedling when I skipped a day of watering, because I thought I might be overwatering. I gave them all a good watering and got five out of eight back. A few of the survivors have some damaged leaves but seem to be plugging along nicely again.

A pic would definately be helpful.
