ikafka ..... some of my plants have done that. It's been over a month and are pretty much the same. Some are putting on flowers. I've never figured what's up. People here have said broad leaf mites..... I've sprayed .... used lady bugs...... PRF said some of his plants do that from time to time and he doesn't really know why.
I hope someone can be of more help. And if you figure it out please post back.
Peace and good luck,
P. Dreadie
