They spouted in the trays grew for three weeks transplant to there own pot and really have not changed that much . Seed from three people what I will do different next year seed smaller in the seed starting trays and thin from there instead of seeding a tray and transplanting from there and grow lights . Never have used them and thinking that is the problem . But started tomatoes around the same time but there been in the ground for a month
Do you have any pictures? Pictures are always helpful.
I always notice a slow down period after any transplanting. It's one reason I seed direct to the cells and thin down, I hate disturbing the roots any more than necessary. By transplanting to larger cups, you've given the roots more room to spread, and hopefully the seedlings are just slightly dormant up top while the roots are spreading out again down below. That's what seems to happen when I transplant to the patch anyway. If so, they'll take off pretty soon.
Just to be safe, let them get fairly dry, then give them a dose of one tablespoon of Epsom Salts per gallon of water. Then start your feeding program with some water soluble fertilizer, like a 20-10-20. Don't over water. Water from the bottom. If you water from the top you can end up with compacted soil and cause spiral root or damping off. You have a full month left to turn them around and get some size on them. Make sure they are getting plenty of light. If you are leaving the lights on 24/7, I see a difference when I switch to using a timer and cut the lights off at night.
