Hi,

This Foxfarm feeding schedule will be helpful for you to get the ratio of nutes correct and give you something to go by. I'd mix them up as directed with the amount of suggested water and then dilute with more water if necessary to get your desired strength. I've also had some salts build up when using TB so I'd only feed every other watering and even do a flush every couple of weeks to keep things happy.

Good Luck!
