They need to go outside. Start with just a couple of hours sun at first and work up to full sun over a week or two. Bring them in at night for the first week or so, or provide them some protection like a cold frame. Normally you should expect to be planting out around now, but the forecast looks a bit chilly at night so no rush.

Forget lights for this year, but do get them some sun so they don't stretch any more than they already have.

if they are in peat moss, they must have fertilizer, at peat has no nutrients. 10-52-10 to develope a good root system for 2 weeks, then switch to 30-20 fert. for long as u want.
