Currently running a low tech/low light 50G set up w/ 2 x 48" T5NO bulbs (28w each bulb). Recently purchased a variety of Anubias for the tank (most within the past 2 weeks). I'm dosing the tank 1 x weekly with Flourish Comp. I also recently started dosing the tank with Excel (5ml daily). It seems like the higher Anubias leaves are starting yellow (nothing extreme). Could this be caused by the Excel? I've read that these plants don't like high light (which I don't have), so I'm a bit puzzled as to why this is happening. Possible deficiency?
I should also mention that my photoperiod is 10 hours (should it be reduced to 8?)
