NEVER EVER EVER CUT LEAVES.

EVER

EVER

All it'll do is shock the plant, and then it'll slow down all growth to repair the damage you would have done.

The plant is smarter than us, it'll sort its own problems out. Let the leaf die and fall off, if its evern going to.

You need to be more worried about WHY its going yellow.

In this case its ok, cos its the first 2 leaves and they normally die off, but if it happens to other plants, be worried.
