If the two are in the same row(horizontal) during any week on the schedule, it means that they can both be added at the listed amount during that time. But I believe after a week or so it will say to NOT add the LK.

Hope that helps.

ForgetClassC Reviewed by ForgetClassC on . Botanicare fert question I bought the Botanicare fert pack for soil. I am 1 week into flowering stage so I am using the "Pro Bloom" but my question is can I also mix in the "Liquid Karma" at the same time? On their feeding chart its show Liquid Karma as optional so I do not know if I use one over the other or can mix them together at the same time. Any insight is appreciated. :) Rating: 5
