Leaf Trouble- Help ID, Please!

[kath]

I've been pulling off a few fairly new leaves from my Starfire Isis Cherry tomato plant for the past week or two because they have appeared to be turning yellow and becoming speckled starting at the tips. In hindsight, I wish I'd taken pics of the first ones I pulled because they were more affected than the ones I spotted today.

This is something I've never seen before so I looked up viruses in general but can't find anything that looks the same. The leaves on the whole plant look puckered or blistered so I was wondering about TMV. Is the puckering maybe normal for this new variety? The vast majority of the leaves look very green and healthy.

I'm really tempted to pull the plant in case this is something really bad that can spread but don't want to be too hasty.HELP!

TIA~
