	Pale yellow/green growth
illustrae Fish Addict Posts: 820 Kudos: 876 Registered: 04-May-2005	I recently got some ludwigia repens, and it's a very healthy bunch that is still growing, but the new growth is looking very pale compared to the earlier growth. The leaves are very close together on the stem and not leggy, so I don't think it's a light problem, unless they're getting too much light? What nutrient are they missing? Tank uses no CO2, and has 2+ wpg for 13 hours per day. I dose with Flourish, Excel, Nitrogen, Phosphorus, and Potassium every week. Hoping that there must be a word for everything I mean...

I just started adding Flourish Iron myself a week ago (in addition to regular Flourish, which turns out has very little iron), and I can definitely see a difference in the red plants. The new leaves in ludwigia in particular are now very healthy and very red. -P

So it's not available for the plants for a long period. If you have the Iron then try to dose that. If problem persists increase the dosage of regular Flourish as another micro nutrient may be lacking. Extra micros usually get a good response. Some days you're the pigeon and some days you're the statue. Remember that age and treachery will always triumph over youth and ability.
