  1. Alright might be jumping the gun here a little but a few of my seedlings are are possibly showing a slight deficiency. The newest growth is becoming yellow.
    Plants are under 400 watt hps. Grow medium is 3 parts organic potting mix, 3 parts worm castings, 4 parts vermiculite.
    I have been watering with rain water. Havent been able to get a ph meter yet. Next week for sure.
    Haven't fertilized yet.
    ideas or suggestions? Thanks a bunch dudes and dudettes!

  2. New growth comes from the stem and will be a brighter green. First thing you would probably see would be n def and that starts with yellowing of the tips first on older growth

  3. They look healthy to me.

    Sometimes new growth at night looks lighter green in the morning because it hasn't seen light yet.
  4. I'd transplant out of those cups for improvement.
