Hydro buddy anyone?

Hi guys,

Does anyone have experience in mixing their own chemical fertilisers?

I installed hydro buddy and purchased the following :

CalciumNitrate
Potassium Nitrate
Iron DTPA (10%) 1kg
Monopotassium Phosphate
Magnesium Sulfate
Manganese sulfate
Sodium Borate
Zinc Sulfate
Sodium Molybodium


Now I read this has everything I need to make my nutes, but I am not sure if I am missing copper??

Thanks for any assistance. Also what formula should I start out with on hydro buddy?
