Are you using fertilizer?

Getting to cold at night can make them drop as well, but I don't imagine it gets very cold there.

No. It is not cold here.

And the fertilizer, I was using one, NPK 8.8.8 EC Fertilizer. But an agricultural engineer said that this fertilizer just grows the plant. So I don't use it anymore. According to him, I should buy a fertilizer that have P rates high. I ordered a 10.30.10 NPK fertilizer.

The constriction/discoloration is a tip off but I can't remember the cause. Sorry!

Found it! click here> Banana Pepper Plant Wilting & Stems Turning Black It doesn't exactly match your symptoms though.

Day temp. 86F least - 93F highest.

Night 67F - 74F.

Humidity %34-%51 ( To the forecast )

I don't think that too much watering.

My fertilizer is 10.30.10 N.P.K fertilizer. And it is also contents trace elements. ( Actually I started to use it today :/ )

I 2x enlarged the pot last week.

And air circulation is very rich.

But the insects, I have never seen any bees or this kind insects. I'm pollinating the plant on my own. With a paint brush. And actually I don't see any polen. There isn't any yellow dust.

I think it will start to give after this fertilizer. What do you think?

And is the temperature too high? Because sun is very strong and at least 4-5 hours a day, plant taking sunlight directly.

I can put it into indoor if it is necessary. Air conditioner is open 7/24 at 25-27C degrees.

Yesterday, I started to using N.P.K 10.30.10 EC Fertilizer. I sprayed to the leaves. When I start to see the effects?

I think they forgot you..

I was having the same problem with my peppers (lemon drop and also pepperoncini). I had added a fertilizer that was high in P before, and then added some general all purpose 'fertilizer' (actually I diluted good potting soil dirt in water (a spade full of dirt to one gallon water) and used that to water the plant. The diluted dirt water seemed to help them out more than anything else. It took about a week and then I noticed that the new buds were not turning yellow again.

Hope this helps!

Oh, also I usually don't see insects pollinating my peppers either, but I think that's because I don't get out there until later in the day, pollinators seem to be active (around here anyway) early in the day).

Thanks

this happened with my habanero plant, actually it still happens but ive gotten about 20 peppers off of it with about 20 more not turned orange yet. My habs started flowering in 90 degree weather and I lost a lot of would be peppers but I just watered it everyday used fertilizer like once a week and just made sur it didn't wilt and its been turning our a good deal of peppers now. I think this is kind of unavoidable your/re bound to lose some flowers just be patient, they will come. Good luck!

also I used neem oil solution for pest control and as a fungicide and it works really well

i use soapy dish water for pests. in a spray bottle. gets rid of aphids.. recently had some stink bugs, but noticed they were eating the aphids, so i left them be and now the aphids are nowhere to be found, and the stink bugs have left.

small bee's and these fly like bee bugs seem to have found them, and frequent the flowers. every day, their small like a skinny fly, but green. never seen them b4.

I had heavy flower drop early on, but i was told reapers will initially drop the first flowers. now i never had actual forming peppers drop, just the flower would turn yellow, mostly the stem, the flower stayed white, then you touch it, and it would fall.

i started touching flowers daily, to help them pollinate, even those these are outside.

i use two sets of nutes. pure blend pro and fox farms open sesame.

i found the high nitro content of pbp caused this to happen, but the plant would put out a bunch of vegetative growth after 3 days from feeding.. my reapers are a solid 4 feet tall and stems are strong in only 5 gallon buckets.

if i did a light dose of the ff os... i had more flowers pop up.. this stuff has more p and much less n, which was my problem i feel after experimenting, i've never grown peppers prior to this season. lighting water temps all being the same, switching nutes showed drastic differences.

high nitrogen levels help them grow, but phosphorus and potassium helped them flower very well.

my reapers and Caribbean reds are all very happy. they usually get morning sun, then they miss the heavy heat of the mid afternoon, then get evening sun. i try to not let them wilt, wilting seems to have slowed their growth.. they will be moving late sept. into an indoor tent under artificial lighting tho. plan to run them year round.

heres a recent harvest of some reapers. the far left is a Caribbean red, its not a reaper. those seeds are from the Caribbean as well. i was just lazy with moving them. i've started keeping seeds and peppers on wax paper, then moving them to vacuum glass containers and putting them in the freezer.

i had some reapers on a scale, but lost the shots, ranged from 9 to 27 grams.
