When plants lose their chlorophyl and turn white, what is this a symptom of in terms of nutrient deficiency?
The reason I ask is because my floating elodea densa are turning white in places and i'm a little frustrated not knowing what is causing it.
I dose 10ml of profito and 10ml of ferro from the Easylife fertiliser range as well as 10ml of Fosfo and 5-10ml of Nitro per day. There is always sufficient c02 injection at lights on.
What am I doing wrong?
Edit: The following point is a stab in the dark but could the chlorophyl depletion be down to an incorrect concentration magnesium in the water. I found the following statement on the internet with regards to magnesiums role in photosynthesis:
"Magnesium is present in natural sea water in a fairly high concentration 1350 1500 mgL and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants algae and coral would not be able to survive.
Magnesium also helps to maintain the correct combination of calcium concentration and alkalinity as it slows down the formation of calcium carbonate which can absorb many important trace elements within the aquarium."
