I planted tomato seeds into a seed starting tray (one of those 72 pro hex ones) on May 8th and they germinated after only about 4-6 days. They've been growing well under led shop lights and I've been watering daily but recently have started flopping over and being weak. Why is this happening and how do I fix it? Is it possible they need to be put into a larger container at this point? The leaves look healthy enough and they've been growing under an led light for 16 hours a day.

    Plus a photo of the tomato plants would be very helpful – Bamboo May 29 at 13:19
  • MORE LIGHT! Unless it's fungus; then it's time to start over. – Wayfaring Stranger May 29 at 14:19
  • it sounds like transplant shock. – black thumb May 29 at 20:54
  • I suggest gently removing one plant from the cell (cut the cell if you have to - you want to see the roots. My guess is that they're root-bound, but as Bamboo noted, a photo would really help. – Jurp May 30 at 2:45
  • What kind of LED lights are you using (blue and red? "Full spectrum"?) The wrong wavelengths may cause issues with growth. – Jurp May 30 at 2:51
