My Strawberry Plants
From what you indicated, yes the pH is probably too high and excess fertilizer will result in no blooms. Strawberries also do better in the cool weather in the spring, and some varieties do not bear fruit in the summer.
However, from your pictures, it looks as though there may be spider mites on the leaves. Turn the leaves over and look for slight webbing on the undersides of the leaves. You can use insecticidal soap and just a stream of water from the hose control. Do not use insecticides, as that will cause an increase in spider mite populations.
