OK, I just checked my seed starting "soil". It's Burpee Organic Seed Starting Mix. It has coir instead of peat. I've never used anything with coir before so I hope that's not part of my problem. The package says to fertilize after 4 weeks, so I'm thinking that I will go ahead and add some fertilizer tomorrow How should I mix the fish emulsion if I go thaat way? I'm also changing out my grow lights-I think that they are at least 4 years old. Spring is the only time I use them so I kind of lose track I think I need to put the date on them:). I got some new cool and warm white bulbs today so that should help. The seedlings look a little leggy even though they are really close to the lights. I'll turn off the heat mat and keep the greenhouse cover open, as well as add a fan. Thanks for the suggestions. I'm adding a few photos. The one of the seedlings is pretty bad, but you get the idea.
Here are some photos of my set up in my basement:
Thanks again!
