Plant Help

[Saint Cuthbert]

I have two tanks - a 65litre and an 80 litre. They are both heavily planted - one is cycled but still young and the other is only two weeks old. They are kept at 25 C. There are a variety of plants in there. Planted with pebbles around the roots and a sand substrate. I have been adding leaf food, and lights are only on 8-10 hours a day. Not near any natural sunlight - but the leaves keep turning brown - almost like they are dying. It is only on certain leaves - but too many to cut off.

it may be lack of iron in your water. do you have a substrate under the sand like eco complete etc..?

What 'leaf food' are you adding.
