This is about the worst tomato so far with caged position 11, another Big Boy, being a close second.  This pic taken on 8/28.  Although it looks barren there still is healthy growth and second wave tomatoes.  The last harvest (8/29) was 7 good over two days and it looks like things are slowing down.   This might be the dividing line between first and second harvest.  Second harvest looks very probable but mites still present.

Update 9/2: Tiny two tomato harvest today which is first since 8/29 so the lull continues.
