    I've been starting an area of HC with the dry start method and everything has seemed to be going fine but I've started to notice a little bit of yellowing on the older leaves. I'm not sure if this is a sign of a problem or just normal. My gut tells me their is something amiss, but all of my dealings previously have been with terrestrial plants.

    Some background on the tank, the plants were started the first week of February. They are planted in Flourite Black and I've been using a diluted standard fert a few days a week, applied with a mister, over the HC, Anubias and Java Fern. The Anubias & Java Fern look great, no yellowing at all. Lighting is 12 hours per day 24" from the plants.

    Any ideas?

    Thanks,

    Chris

    I'm going through the same problem, but with new submerged HC. It looks just like the picture you've posted. Algae seems to favor these leaves after they start turning yellow, which is becoming a real pain. I suppose this rules out insufficient CO2 as a cause, if nothing else.
