My Speckled Romans are suffering a wilt from the top. I've been out of town for a few weeks but we've had sufficient weekly rain so was surprised to see these plants looking so pathetic. I took a close look today and discovered the wilted branches all look to be split on one side, and perhaps healed over. There isn't an active open split as seen in the pith disease photos. I'll take a closer look at the bottom stems tomorrow. From a glance they appear fat and vertical and there is a lot of foliage. There aren't a lot of blossoms and no set fruit. All other tomatoes (various varieties) have fruit coming along and I'm already eating the Sweet One Millions (gotta love those little guys).

Any thoughts?
