Don't use chaching or beastie with anything else. Use them as a ONCE a week stand alone feed.
Cha-Ching is your finisher feed. It's high in K, so you want to use it at week 7 and 8 to stack on resin and bring out the terps.
Beastie is your bud growth booster. You want to use this about week 4 and 5 when your buds really start to grow.
The stuff is super concentrated. Do not over use it or use it with other feeds. If you do a feed on a monday, plain water for the rest of the week.
