Banana leaves splitting
I've got a Blue Java banana tree growing in a hydroponics system. It's been doing great, and is about 12 feet high. Lately, the new leaves are splitting as they unroll. After an entire leaf unrolls, it looks as if it was split apart by wind, tattered. I'm wondering if this may be due to a nutrient deficiency, or some other cause.
The nutrients I use are General Hydro flora, and my concentration is 1200ppm
I appreciate any insight.
