Not really Mike. The day length varies just a little.
About an hour ago I asked the owner of a nursery here, which is pretty knowledgeable. She says that it is just a problem of feeding. She recommended that I should add urea and 12-24-12 (which is very readily available here). 1/2 teaspoon or each weekly. She has over 25 years of experience…
I am guessing that weekly feeding has to do with the fact that we get a lot of rain, and since I have this in pot, nutrients get washed away…
