My amish paste tomatoes are growing very good but when they start getting ripe they develop a soft spots that seems to be rotten any ideas on what to do to prevent this? also how to keep the king parrots away from them

Need a pic of the tomatoes, if its blossom end rot, calcium deficiency or water problem (unusual in AP,the water).

From what you have described seem a fungal disease called blight, it might be too humid the environment.
In organic gardening you can spray leaves with Copper but definitely NOT in AP!
No treatment available in AP, just increase air flow and trim some leaves, a 4 year rotation cycle to destroy spores left behind in the media is necessary.

If they are rotten and black on the bottom of the fruit its blossom end rot. Its not a pest, parasite or disease process but is a physiological problem caused by a low level of calcium in the fruit itself. Calcium is required in relatively large concentrations for normal cell growth and in most AP systems is not an issue. When a rapidly growing fruit is deprived of calcium, the tissues break down, leaving the characteristic lesion at the blossom end. Blossom-end rot develops when the fruit's demand for calcium exceeds the supply. Certain conditions reduce uptake and movement of calcium into the plant, or rapid, vegetative growth due to excessive system nitrogen levels. Ive used cuttle fish, buried at the base of a suffering plant before with good results.

Yes, a picture would help. Also, it could be the notorious white fly that make similar fruit damage and chlorotic spots. Are the leaves yellow, curling, and/or drying as well?
