I have six banana plants in my back yard. Two of them have recently started putting out pale, stunted, and mis-shapen leaves. The mystery banana's main pseudostem looks good, but the leaves of the pups have been affected. The Raja Puri has been affected in both the pseudostem and the pups. in the Raja Puri's pseudostem, in addition to being pale, stunted and mis-shapen, the leaves are twisted and tangled up in each other. The other 4 bananas are doing just fine. All six bananas receive the same growing conditions. The three pictures below are of the Raja Puri.

All my bananas are on a drip irrigation system. At the beginning of June, I increased the watering frequency from one hour every other day to one hour every day. During the second week of June we had lots of rain all week (the drip system was off that week). The problem started about the same time I increased the watering. This suggests an over-watering problem, but I watered the same two plants daily during June, July, and August last year and didn't have this problem. I have reduced the watering back to every other day.

So what do y'all think? Is this an over-watering problem or something else?

My namwah have the same pale green leaves, and often shredded or mis-shaped upon unfurling. I am pushing mine hard with fertilizer and think that may be it.. many have done it for a few leaves, then resumed normal cigar leaves. After a day or two, the new leaves become dark green like the rest. If you are using a slow release fertilizer, increased watering may be pushing more nutrients to your plants.. I wouldn't worry a bunch about it.. im betting it will sort itself out just as mine have.

This is lack of fertilizer ... specifically nitrogen. Apply granular balanced fertilizer for vegetables to the ground and then foliar spray with urea at 2% nitrogen or Miracle Grow (24-8-16) mixed to 2% N (76 g/gal of water) weekly until the leaves are normal again. .... Foliar spraying will show improvement over night.

Looks like Boron or Calcium deficiency.

Although present in the soil, the uptake of these minerals may be impaired due to rapid growth caused by excess nitrogen or rainfall/irrigation. High PH can also prevent/impede the uptake of boron and calcium. A few members have reported their well water or city supplied water had a high PH which effected their plants.

Deffinately need fertilizer lots of great ideas from earlier posts just remember to water in well whatever you use otherwise you can burn the plant.
