I have been thinking of cutting the dead leafs and probably will but the problem will remain as its slowly progressing. They are grown under fluorescent lighting at 24C and with high humidity(and bad air circulation unfortunately). |
I use 'enhanced spectrum' digital 400 and 250 hps lights from Hid Hut (HidHut Website). Plants love these! The banana's just keeping putting out new leaves. We have used them many times over the years. I also keep the ceiling fan on, night and day for air circulation;

But I do have some plants in the garage that does not have plant light, so when it is nice outside above 45 and/or if it rains, I wheel them outside-to get sun light or water; leaves must have light to stay green. Here is an idea to easily take the plants inside and out:

If your banana continues to deteriorate, I'd pull one of the banana out of the pot and check its root; is it dry or does it have root rot? I'd change soil if necessary and especially if there is a sign of fungus; spray with some type of Plant Fungus Solution. And clean up all dead leaves and dead discolored p-stem to avoid spread; let it dry out and wipe any fungus appearance w fungus solution; air circulation helps too.
Also, make sure there's no spider mites or other bugs too. I'm only saying this because I'm battling with spider mites; its turning my plant leaf yellow and hurting them, and so every time I see these annoying bugs, I just cut off the leaves and off it goes to the trash can; by doing these, I also get rid of the eggs from multiplying.
