<p><br></br> George,</p>
<p>I had this problem last year with black spots and I thought it had to do with humidity because the green house had poor ventilation. This year, I screened in the green house to open it up a bit and bought some green house fans to see if it would fix the problem.</p>
<p>There is lots of air movement and less humidity but the black spot problem came back. I have been spraying the effected plants with a Potasium Bi- Carbonate and Molasses mix for the past few days and I…</p>

<p>There is lots of air movement and less humidity but the black spot problem came back. I have been spraying the effected plants with a Potasium Bi- Carbonate and Molasses mix for the past few days and I have not seen any new black spots. So thats a good sign.</p>

<p>Alex,</p>
<p>That is very kind of you. Unfortunately I live on Long Island, NY. It would be a bit of a trek. I have been looking at all of the plants (Pak Choy, Peppers,Lettuce and Honey dew) growing in that particular growbed and I did find some Earwigs. But thats about it. The Pak Choy and Pepper Plants are not being effected. I have been searching the web and my gardening books but nothing definitive so far.</p>
<p>Perhaps a microscope purchase is in order.</p>
<p>Thank you </p>

<p>If you live in the Illinois area, you're welcome to come over with some leaf samples. I can put 'em under my fancy, schmancy microscope and we can figure out what exactly is going on :)</p>

<p>They are TINY. I'm a young guy with 20/20 vision and I have a hard time making them out without a magnifying glass. Check the less damaged growth on your plants.</p>
<p></p>
<p>It's also possible that it could be spider mites, but I'm leaning towards thrips, especially if the leaf damage has a silvery glint.</p>

<p>Thanks Alex,</p>
<p>Upon initial inspection, I did not see any bugs. But I will give it a more thorough inspection after work today.</p>

<p>Your lettuce looks like you have a thrip problem on your hands. Take a really close look at some of your leaves (preferably with a magnifying glass or microscope) and keep and eye out for tiny, elongated green bugs.</p>
