Ok so I am having, what I feel is major problems and I can figure out why.

Now here is the problem.....
I did 3 batches of Autoflowers. The first batch is the center 6 seedlings. The other 6 seedlings surrounding the first 6 were planted 1 week later and have almost caught up and are at the same stage as the originals. they COULD pass them but I am very nervous.
The oldest seedslings look yellowed, with dark edges of the leafs and are drooping down and not aimed upward.
At first I was doing the water bottle spray technique in a circle around the base of the seedling maybe 3 inches away keeping the top damp. Then I was told to water them so I watered them pretty damn well. Did I overwater them too early or am I not watering enough??? First timer here obviously.

Please help!
Love JF

If your light is dimmable, turn the intensity to half and hang 36in at least. If not dimmable raise farther. Water like half a liter around the seedlings. You’ll start seeing them bounce back in a few days trust me.
