Hmm
Could this be boron deficiency?

Tip burn is techincally a calcium deficiency, however, practically, it's a water relations problem. Calcium ions are carried by water through the plant to growing tissue. But not very efficiently because of the size of the ion and the passive movement. So if you have rapidly growing tissue, high temps and less water available, you can get tip burn. In my experience though, its always at the edges of the leaves. If you have a problem with the row covers, it'll cause abrasion on more than just the leaf edges. Hope that helps you sort it out.

My spinach (Emu F1, now baby leaf size) is showing
some leaf tip damage, but it doesn't look like
actual tip burn and I believe my calcium levels are
okay. It has been covered by floating row cover
since planted (for leaf miner), but now I'm
suspicious that the row cover is causing the damage
(since it seems to only be upper tips that would
have come into contact with the fabric). Is
spinach too tender for floating row cover? Should
I hoop it? Or should I be looking for some other
culprit?
