Doug:
Sounds like your plants may have chlorosis - an inability to
photosynthesize. You soil could be tying up nutrients. Perhaps it's
the wrong pH for veggies.
Vegetables require a pH range of 6 - 7 (I think the perfect pH for
veggies is 6.2). So, make sure you've planted in a good, sterlie
potting medium (vermiculite, perlite, peat, etc. - something like
Hyponex).
In the interim, yous should use a fertilizer high in nitrogen. Soils
which are too acidic (low pH) tie up nitrogen (and calcium and
maganesium, among other macronutrients. A lack of calcium inhibits the
ability of the soil to use magnesium - which can cause some forms of
chlorosis).
Harry Jiles - is that the way you see it, too?
