Tomato Help!!

Tomato Help!!

The last few days I've been noticing this on my tomato plant: Poor Tomato It's not on the top leaves--it's on the the leaves on the bottom working its (whatever is causing this) way up the plant. Luckily this is the tomato that is in a pot and hasn't joined its fellows down in my garden yet. Also, there seems to be a similar problem occuring on my patch of Forget-me-Nots in the front of my house. No sign of any pests on the plant. Does anyone know what it is? And what do I do to fix it? I have a very busy weekend coming up and I'd like to get this problem on its way to being corrected before it's too late. These are tomatoes that are being organically grown--so I'd rather not spray them with any pesticides as that would rather defeat the purpose. Thank you for your help.
