Question
Hey Mike. Thanks for response regarding the yellow leaves and the black dots. Plants are growing great now, reaching 6' or so. Pinched the tops off so the plants would concentrated on fruit instead of height.

Anyway, another questions. Got some tomato plants in earthboxes. All growing great. Though a couple of weeks ago, I noticed the very top leaves of the cherry and yellow pear tomato leaves were starting to turn bright yellow. There is no evidence of any disease and doesn't seem to be affecting the growth, blooms, and tomato production. I have searched and searched the internet and couldn't find anyting about this. Any ideas?

Answer
Kevin, this is usually a symptom after heavy rains.  The excess water in the soil prevents the roots from drawing in nutrients for a short period.  This condition corrects itself in very short order.  I would not worry about it.  Just make sure you are fertilizing with a solution high in phosphorus.  Most of the fertilizer companies now sell products specifically for fuit-bearing plants such as tomatoes and peppers.  This will help replenish the soil.

Have a good evening.

Mike
