Was pruning my tomato plants and found this.
Side-shoots from the centre of the leaf stem.
I think someone else on the forum had the same weird-ness.
Looks funny eh?
I recon its from over feeding.

Very common. Possibly over-watering?
I've got the same. There was a question about this on a recent "Gardener's Question Time". They said not to worry about it.
But remove them.
I removed some of those this morning......I have never had this happen before!
Mostly late in the season.
