Ok - my 2 tomato plants now have about 7 tomatoes of varying sizes between them. They're all still green, but I've been noticing that the leaves on the lower limbs are beginning to look unhealthy - not really wilted, but certainly not firm like the newer upper leaves. Some are also turning a splotchy, anemic looking light greenish/yellow beginning in the centermost part of the leaf. Each plant is about 3-1/2'.
Just now, I've seen a very busy small vividly colored small bug that's yellow-gold with multiple black spots. Except for the color, it resembles a small lady bug. And it's very busy, running back and forth across the top surface of the leaf. So far, I've only seen one.
A quick Google search rendered no specific info. Can someone tell me if this bug is friend or foe? Would it be causing the deteriorization of the lower leaves?
