Fruit tastes good but berries are unsightly
It's probably a fungal infection or an environmental issue. Heat and humidity can wreak havoc. Be sure to clean up any fallen leaves or fruit from around the plants. Keep them mulched so the fruit doesn't touch the soil.

There is a lot of leaf growth but few flowers. Would all the leaves be preventing the sun from penetrating through to the flowers? If we fertilize the plants as often as recommended, won't the leaves grow even more?
A lack of flowers can indicate not enough sun. Strawberries need 8 hours of sun each day to produce well. Other reasons include improper watering, excess nitrogen fertilizer, and pests or disease. I included an article below about fertilizing that should help.

I purchased Fragsria strawberries from Park seeds catalog 2 weeks ago and my strawberries are doing off one by one. I live in Florida,zone 10a. So I have very poor sand and I made my own soil from local sand soil, compost and worm casting. See first picture. I was hoping to fine what pH strawberries perfer. I test the soil I made and the pH tested at slightly acidic, second picture. The other tests are as follows: nitrogen, high; phosphorous, very low to none; potash, very low. I used HoldAll soil testing kit. Also, I used Gurney's strawberry food 4-3-4 when I planted them.
Strawberries in your zone 10 should be grown in winter. Spring and summer is often too hot for strawberries in your area. The soil must be kept moist in hot areas. Soil pH should be 6 to 6.5. Be careful not to overfertilize. Here is more:
