Onion Leaf Yellowing

Does this mean they are short on nutrient? Should I feed?
It's not all leaves, just on some outer tips.

Could signify shortage of nutrients, water or even disease.

or pests: mine are showing signs of moth attack (chewed holes & frass as well as droopy yellowing leaves)

Thanks both I will have a closer look see.

A nitrogen feed wont hurt

[VirginVegGrower]

Will do. Just got back from lottie and everyone else's are the same so figure it's natural ageing. Bulbs like fine - fattening up.

I had some plants with yellow tips, a friend diagnosed them with magnesium deficiency caused by poor soil PH (caused by terrible brand name soil grr), and we gave them a light spray with epsom salts solution (one tsp to a gallon). and adjusted the soil PH. This seemed to do the trick! There are probably a few things it could be, this was just my experience with some particular plants.

I did wonder if magnesium deficiency could be an issue, as I have sprayed cukes before with Epsom salts. Never heard of it in onions though. My shallots are also yellowing but this is pretty normal for them at this time I think.
