I think, that's my problem too. I have to add more light.
Only have one 15W strip.

I have the same setup. 20 gal planted tank with 1x15watt tube over it, I
had slow plant growth and poor colors in the leaves. After adding a 2nd
15
watt strip light over it, my plants took off and color much improved. I
am
currently very happy with the tank and regularly have to prune the plants
to
stop the overgrowth.

least 2W / gallon for low light plants.
I think 15W is not enough.

If your fish are anything like mine they will find your efforts
wonderful.

Wonderfully tasty that is... ;-)
