pale leaves, dark green veins
I've never posted here before, and am not up on all the organic gardening techniques - but have always considered myself an earth friendly gardener.
Can anyone tell me what I'm doing wrong: I got a load of aged chicken manure and worked it into my beds this spring. I also mixed in some seaweed meal. Instead of my plants looking great, some (not all) have pale leaves but with dark green veins.
I should probably add that my soil is very sandy and every year I add compost or peat moss to it.
Thanks for any advice,
