Noob in need of serious help!!!!!!!

Alright... So here is what is happening. I had a successful grow on my very first go around. (beginners luck!) Every time after that my babies have been curling up and just die. Its almost like the leaves try to turn upside down. I am following my watering and feeding schedule as normal and i have been poking around on here for awhile and havent found anything that seems to really fit the bill.

The first picture here is at 10 days. they were looking great. they were under a shop light and things were lookin good! Ph was a bit high at 6.9 and they are in miracle grow soil.

The second picture is after 3 days under a 1000w MH light. nothing else changed.

i've seen that happen when the seeds were planted too deeply. they germinated and a few days later began wilting and then die. also, careful with the watering. when they are that young i water them with a mist sprayer to barely dampen the soil. GL

Can I guess it was the 1000w , how close was it ? You need to keep them separate in future , put a seedling into it's own pot , try try try and try again learn from mistakes .

Thanks for your responses. I'll try being easier on the water.
