Help - all of my seedlings are suddenly dying

bny806February 23, 2014

This is my first year at this - growing indoors with heat mats, grow lights.. everything had been growing so well until the bottom leaves started to yellow.. I had some purple underneath the leaves.. and then the top leaves yellowed and now are turning brown - they all look pitiful! Any advice? I attached pictures of the spots/yellowing on their leaves..

Thanks

Is the bottom heat still on? If so, turn it off.

Turn off the heat. How long do you keep the light on them?
