Hi guys!
I have a Dwarf Cavendish - Musa acuminata that has been losing its leaves rapidly (more than normal). I lost 2 large leaves last week and now 3/5 remaining leaves are rapidly yellowing and browning. The new growth exhibits browning also. What might be the problem?
I only water when dry and fertilize monthly. She is under growlights to make up for lack of light in the winters here in Canada. There were spider mites but I got rid of them mostly and wiped the leaves down recently with really diluted alcohol get the dust and webs out of the leaves.
