are they inside? what type of light setup, what fertilizers, what growing medium, what are your temperatures like? Pictures would be nice also

I hope you are in Singapore so the temperature may not be a problem.

I have similar problems before and now, one of the causes of the problem I have are over watered. From over water there are so many possible problems we may have to our plants specially container plants. I knew that over water kill my plants but as a new hobby gardener I cannot follow the guideline correctly.

Like "thismembername" mentioned, some basic information of your plants with picture should be very helpful to the forum members to help you.

We have so many professional gardeners so probably they can help you.

just imagine immature flower buds where mature ones should be.
Right now in Singapore it is a little cool (certainly not enough to kill plants), but weather should heat up soon.
My plants receive indirect sunlight during the day, but at night, these orangey lights switch on at my corridor, which probably helps.
