Browning plants... arg!

At least 2 of the plants are aquatic. But you will need to test your water completely before a dosing schedual can be setup for ferts. Chances are with more light your plants burn through what ferts are availabel much faster and then don't have enough to continue.

If you don't have a Master test kit then take a sample to a fish store and have them test everything (calcium, phosphate, nitrates, etc...). And then post again with that info as well as your water change schedual.

Holes in leaves is usually a potassium issue. Browning could be many things.
