Dull-colored Cryptocoryne, possible nutrient deficiency?


My Cryptocoryne (I think it's a green wendtii, but I'm not sure) is growing dull-colored, narrow leaves, as you can see in the photograph. When I bought the plant, its leaves were broader, and a very bright yellow-green. I have since trimmed the original leaves as they became overgrown with algae, so you can't see them in the photograph.

Could anyone speculate as to whether the plant is showing a nutrient deficiency?

I dose KNO3, KH2PO4, and Plantex CSM+B; I am using a Fluval CO2 20 in a 10-gallon tank (which, to the best of my calculations, brings the CO2 up to around 15ppm), and T5HO lighting.

I don't think that's wendtii...Could you please take a better picture? Also, most crypts have that kind of greyish dull color. Nothing is wrong.

Could be the plant was being grown emerged when you bought it or shortly before. I am growing some wendtii submerged and emerged. The emergant growth tends to be broader and darker, while the submerged leaves tend to be narrower and "reach" towards the surface more, so I am not positive this is a nutrient deficiency. Could be normal, though I would be curious to hear input from others.

I'g guess it is just adjusting to being under water. Give it time I think you will like the color.

Don't hold it. Stack things (boxes, books etc.) to get the right height. Hold the phone as little as possible so as to keep it pointed, but not induce shake. Just fingertips.

I'll try that tomorrow and post a better picture if I get one.
