Plants turning brown/red.
I've just set up a new planted tank and after a week the tops of my Ambulia are turning brown/red/lighter. They were green obviously.
I also have a sword in there as well and its already produced 2 new leaves which are also a darkish brown/red.
What's this mean?
Tank is a 3 foot x 18 x 18.
120watts 2 x 6700K, 2 x 18000K bulbs
DIY C02 which doesn't seem to be working just yet.
Laterite and 3mm gravel covered with 3mm gravel.
No ferts yet as its only a week old.
