My serrano peppers have been growing like crazy and then all of a sudden the leaves turned yellow only around they edge, and they curled up a bit. It did this all of a sudden, though it did get very hot here. . . it is 105 today.
This is due to water stress. Increase water ti the plant.
If it is in the ground, try to water deeper (i.e. longer), rather than more frequently. This will help store water deeper in the ground and encourage the plant to grow deeper roots so that it can better have access to water during high heat.
If it is in a container, you may need to water several times a day in heat that high as the water in the container will evaporate quickly.
Thank you sooo much! I increased the water by a couple minutes and they seem to be doing much better
I just harvested a bunch of serrano chillis. Too many to eat that fast. How to you store them?
If you have an over abundance of peppers, you can dry them for easy storage. This article will help with that: https://www.gardeningknowhow.com/edible/vegetables/pepper/drying-hot-peppers.htm
Is there anything I can do to my serrano and jalapeno peppers so that they are hot. I have harvested many peppers this year and none of them are hot. I have them in a raised garden and they have been growing well. I am surprised that they are still flowering this late in the year.
Genetics, water and nutrients can all effect how spicy a pepper is. As you have 2 different varieties that are affected, then it is likely not genetics.
They may have been a bit too dry and that is why they are not as spicy. Oddly enough, part of the reason peppers produce capsicum is to help ward off fungus. Fungus is most likely to develop when the plant gets more water and so a chili pepper will produce more "heat" when they get more water.
Nutrients may also have played a role. The soil may be lacking some of the micro nutrients the plants need to make capsicum or the soil may be too rich, which causes the plant and its fruit to grow quickly and is not able to concentrate the capsicum in the fruit.
My 50 day old serrano plant had aphids, and I treated with a soap water mix (1 tbls/1 quart of water). The ants are gone, but the leaves seem to be less healthy (some holes have appeared, and the leaves seem to be thinner). The back of the leaves also seem to be turning black in some places. The fruit seems fine. I water almost daily. Did I use too much soap? Do I water too often? Is there anything I can do to help?
If the peppers are fine I would just continue to care for the plants through out the remainder of the growing season.
Yes the soap can cause damage to the leaves and plant. I have found that myself, if the soap is applied in the sunlight it can cause burns on the leaves.
You can apply Neem Oil weekly to make sure the plants stay insect free.

I have a potted Serrano pepper plant that puts on flowers then just drops them with no peppers ever growing. The plant seems very healthy but just won't fruit.
This article will explain the possible reasons for failure to fruit.

Yes! Pepper leaves are, surprisingly, edible.
Here is an article that will offer tips on caring for these plants:

I thought it may be overwatering or lack of nutrients, so about two weeks ago I cut back watering from close to daily to two to three days. I also gave a feeding of miracle grow. Problem seems to not be getting better. Photos attached.
