Re: Melon sword not getting enough light?
What type of light is your 10kK? T8? T5HO?
How big is your tank? How deep?
Initially, I would ask if a melon sword is a fully aquatic plant. Secondly, I would ask if you bought it immersed or growing in the air. The reason I ask this is because if the plant is a bog plant (as many sold in pet stores are), it will grow leaves out of the water as well as in the water. However, if you grow a bog plant out of the water and then immerse it, the leaves will suffocate, turn yellow, and "melt" away while the plant puts out new leaves that are suited to its new underwater environs.
Yellowing leaves is also, as you say, an indication of lack of light (highly unlikely, if you ask me, judging by the amount of light visible in the pics at the substrate level of your tank), but it is also (more likely) an indication of iron or other nutrient deficiencies. Shrimp can tolerate many fertz (I dose my tanks regularly), so I would suggest buying some root fertilizer tabs and a liquid plant food. If you're still worried about overdosing on fertz, just do a half dose of the liquid food, but the root tabs shouldn't bother shrimp at all.
