Strong yang Wood ox with water imbalance?

Hello
I know that my day master is Jia and all my heavenly stems contains 3 jia wood, 2 yi wood and 1 ding fire.
As an advice I know that I should use metal and fire to control too much of wood and water only makes the wood stronger.
however I have also been told that I lack water in my element balance with too much wood, metal and fire. so if I had water, it makes my wood too strong but if I add metal and fire then there is too much metal and fire.
what should I do?
Thanks
