I have a 26 gallon bow front. With lots of plants. I have 55 watts of
light running 12 hours a day. I notice some of my plants are dying.
The leaves look like you can see thru them. Like as if it is
disintergrating or something. Other plants are fine. It is strange..
Is that lack of some type of nutrient?

I dose with trace elements and what not....

My question is basically what does the "see thru" leaves mean?
