It could be quite typical of early season buds.
Even very small seedlings will produce buds or flowers, but
they won't often set until the plant is more mature/established.

Where is the plant located? Is it young/old?
Is it in a container, or in the ground?

hi can anyone help its my first time growning a chilli plant, its hard to exsplan the buds are very small and they turn black and drop off, iv got it on my window indoors, its watered 3 time a week the plant is about 12inchs tall very nice green colour, if anyone can help i will be very greatful thanx

are you letting the soil completly dry out before watering? are you using fertilizer? if so what kind and what strength?

Eric

How are you providing enough light for the plant indoors?

Also, if there isn't air movement, it will be more difficult for the pollination.
As a result, you might not have many peppers setting.

Like Eric, I'm curious about your watering schedule. How big is the container,
and what type of mix are you using? This will affect how often you water.
