I've got a number of onion seedlings planting again this year. You can see my set in one of th epics attached. I've had success with them over the past few years doing them this way.
This year I've noticed, more than usual, that the tops of the seedlings are wilting, or sagging over. You can see this in one of my pics also. I'm wondering what is causing it? Years past, I have noticed it on 2 or 3 seedlings. This year I have noticed it on about 12-15 of them. It seems the lower portion is fine, but the top is falling over. To date i've just cut off the wilting portion.
What could be causing this? Lights too high, or too intense, or too much water, not enough water. The soil is not drying out.
I have to do bit thinning, as some of the pots have 2-3 plants in them. But even some of the pots with just 1 plant in them are wilting over.
Open to suggestions, ideas or previous experience this issue.
Thanks in advance.
