Thank you for your question. This year has been a challenge for many gardeners. Cold wet weather followed by hot dry windy weather had been hard on plants. Your first two pictures seem to show some nutrient issues. Both nitrogen and potassium can be flushed from the soil by heavy rains and temperature can affect nutrient uptake. pH (high or low) can also inhibit uptake of some nutrients. Both coffee grounds and compost can affect this.  Also, coffee grounds may not be the best direct additive to the soil (see link). The third picture with the crispy edges looks like some water stress (too much or to little). A soil test would be beneficial (https://homesoiltest.msu.edu/). At least check the pH.

I hope this helps,
