I put a couple of new bunches of java moss in my 10 gallon tank. The lighting is 1.5 wpg and I dose a small amount (like several drops) of Flourish every 1 to 2 weeks. Nitrates are around 10 ppm. I've never grown java moss so I don't really know what to expect, but I just find it odd that a bunch of "stems" are growing and sprouting "branches" along the sides, but no leaves. It's sort of like a bunch of green strings growing out of the original bundle. Has anyone had this happen? Is this how it normally grows?
