Could be overwatering. Not too much, but too often.
Some plants won't put as much of the nutrients into the seed (fruit) if there is plenty of water for the rest of the plant. Roots will also get lazy
as they don't have to grow much to get the moisture the plant needs.
Try not watering them for a while and wait until they begin drooping...make them work hard, they love it and NEED air around the roots, not just
water, then water only every other day or more if possible. Pick tomatoes as they become ripe so the un-ripe ones then get the nutrients.
For next season, protect young plants from direct sunlight until they are about 1 foot tall. Over here (France) it's common to rest a couple of roman
canal roof tiles against the tomato plant stake.
My tomato plants are doing OK this year, not a huge crop yet but more than enough for my needs and if it's anything like previous years they will
keep fruiting for ages right up until winter (starts about end of novenber ;-).
Bon appetite!
