Trystogolf2, forgive me for this, but please refrain from using all caps. For some it is hard on the eyes and for others it is similiar to screaming at the top of your lungs.
Do you mean you are only getting 3/4 the pound/number of fruit you'd expect, or is only 3/4 of the flowers
setting fruit? What variety(ies) do you have?
The first thing I thought of was over-fertilizing. Too much nitrogen (the first number on commercial fertilizers) will cause the plant to look beautiful, dark green, large and leafy but will minimize fruiting. Also, how much sun do they get? They are sun-hogs.
Sorry I can't be of more help to you.
