Tiny Holes In Plant Leaves

[shadowhywind]

On one of my plants, the plant is covered in tiny little holes (edges of holes are brown if that helps any). All of my other plants look healthy except for this one. It may be releated but my onion plant has two steams/runners/leaves that are starting to decay from the tip. Any ideas on what may cause these holes? I was told by a LFS that the water in our area is extremely low in iron, could that cause this?

The plant with the holes is a compact hygro, or at least thats what the other members here said it was, hehe

are you dosing any fertiliser?

The only fertilizer I am adding is API leaf zone, about a half a cap full (5ml) every 3-4 days. It says to add the entire cap (10ml) once a week, but since I have a carbon in the filter I thought I would do a smaller amount but more often.
