Site newbie, here for some advice.I have been growing peppers in Hong Kong for the last 3 years or so with various success. I am far more confident growing in the UK climate usually.
After beating off aphids, spider mites and other problems, the biggest problem now is a weird elongation of the new leaves. And nobody here seems to be able to help. My latest problem pepper is a sweet Dulcetta plant but, to date, this has also effected the following varieties: Habenero, Trinidad scorpion, Numex Big Jim, Jalepeno, Cayenne and Jamaican Yellow.
Plants that I haven't noticed the problem appearing on are: Patio Fire/Apache Fire, Lemon drop.
A bit of info about the grow area and frequency of water/feed: (photos also attached)
Av. temps over the last few months has been 30 - 36 day (70%+ humidity) 25 - 30 night temp (50%+ humidity)
The current problem plants have lived their entire life so far on my balcony in part shade, although this problem has appeared on both roof and balcony plants in the past.
I have watered every other day in this instance, but have also tried less/more with similar results.
I fertilised my original plants with a 20/20/20 liquid feed when they began flowering, but am now using an animal manure fertiliser instead to see if that helps - it doesn't seem to.
Any help or info on this would be greatly appreciated.
