Any help would be appreciated. Picture is a little out of focus, but clear enough to see what's going on. Plant seems otherwise fine, watering every 6 days, feeding with chilli focus as per bottle instructions. It has had a few doses of pyrethrum to keep the aphids under control recently, but wouldn't have thought that would impact on this. Perhaps potassium? Both the habanero (pictured) and the ghost are showing these symptoms.
