I can't get the picture to enlarge, but from what I can see the yellowing could be magnesium deficiency.

Magnesium sulphate also known as Epsom salts . A tablespoon to a full watering can or a level teaspoon sprinkled on the surface of the compost then watered in.
You can remove the lower leaves if badly affected as they will be of little benefit to the plant.

My plants do this every year with no real detrement to the crop.
As 8doubles says though remove the bottom leaves that are affected as they give nothing to the plant, in doing this you allow more sun light to the crop too to aid ripening.
Make sure you leave at least 6 to 8 leaves on the plant though so it can photosynthesise.

I give the greenhouse a good dose of either multi purpose compost or well rotted manure every spring and always get a good crop.
