Thanks Solcielo lawrencia and Raymond S.
The trace mix is from a local hydroponics shop. Our city water analysis show Ca=30+ppm and Mg=8+ppm, I would speculate this is considered by the local shop hence without Mg. I put the numbers in MS Excel to help myself mixing and dosing, and can scale down/up easily. Tank water volume is more likely 19gallon with gravel and ornaments.
