Dutch Passion Seedlings Taking a Turn for the Worse

First time grower; growing organically.

Soil Mix:
1 Part Organic Mushroom Compost
1 Part Organic Soil
1 Part Peat
3 Parts Peat Moss Sphagnum
1 Part Perlite

Organic Tea:
RO Water with Minerals Added
Worm Poop
Bat Guano
SPT & BHO
Molasses

I bubbled the tea for a few days, and then added it to the soil mixture and let it soak for a week.

I germinated the seedlings in paper towels, all germinated well and I planted them in the still moist soil in those brown/thatch planters about the size of those large red plastic cups. I put the seeds root down, using a tweezers, about 1 inch down.

I have the seedlings under 400W ceramic metal halide lamp (more spectrum than HPS and much cooler; all the rave at International Cannagraphic). Since this puts out much less heat, I had the lamp about a 10" away from the seedlings.

The seedlings were doing well this morning, but upon checking this evening, nearly all have fallen over and look quite pale. Longest seedling is about 1".

I think I am overwatering, as I water twice a day and give it a good soaking. When I do water, I do make sure the top inch of the soil is dry.

I am also concerned over the soil mixture... maybe I don't have enough soil and too much peat moss?

I have pictures posted of the seedlings. My wife took a look at them and thought they were underwaterd, so I just gave it a good thorough watering (the top 2" of soil was dry). From reading, I wonder if that wasn't a good idea. I am watering with plain room temp RO water with minerals added.

Any ideas on what's happening to my seedlings? These are top quality Dutch Passion seeds. Room temp is typically 75-85F. RH is 40%. This is in a pretty cold cellar, so I have a space heater about a foot away from the seedlings, pointed away from the seedlings. If I didn't have this room temps would drop to 55 or below with lights off.

I just turned on the CO2 to give them all the help they can get.

Edit: I will have to post pics tomorrow AM.

Sounds perfectly normal.
You have too much light. too many nutrients, not enough heat and co2 will not help you right now. You basically poisoned them.

Seedlings have enough nutrients in them to last the first couple weeks. They don't need much light at first. Maybe 60 watts 10" away. Your root zone should be minimum of 70 degrees and max 80. Ambient temps should be around the same. the closer the temps the closer the nodes.

Co2 is used by plants when temps are up. Does nothing in cool temps. besides they are so small they get more then enough from the air. Think co2=flower

If they are still alive tomorrow I would think about removing them, dig out a small hole add soil that has no added nutrients then replant them a little deeper and support the stem with a toothpick or wire or something. get some heat to the root zone. A heating pad under the container or something.

Once there roots get through the soil and they have a shot at life then you can over water them and burn them with your super duper fert mix and they will be harder to kill. look up flushing, your gonna need it.

Know before you grow.
