If the leaves are turning solid yellow, as opposed to yellow and brown
blotches(blights), you may have simple choriosis, or yellowing, from
overwatering. The blemishes on the bottom of your tomatoes is Blossom
End Rot (BER we call it here). It is caused by a problem with calcium
uptake. The uptake problem can be caused by too much watering, too
little watering, inconsistent watering or calcium poor soil. If the
weather is dry, I adjust my watering schedule to the high temperature
for the day. For example, if highs are only in the 70's weekly
watering will usually suffice. In the 80's, twice weekly. When the
temps reach the 90's, as they usually do here, I water every other
day. If we get a serious heat wave with 100+, I then water daily.

What is your definition of watering? This sounds way too often unless
you are just dampening the top layer of soil (few inches).

I don't have my own definition of watering, just my own method. I
water with a garden hose and use Auto-Maters. I normally fill them
about 3 times, less if they are showing signs of saturation. I would
estimate that it works out to about a gallon per plant. I have used
this same watering method, with and without the Auto-Maters for 35
years or so. It seems to work fine as I never see choriosis or plants
about to keel over in the heat.
