this is my first grow and im just about to switch my plant into flowering. i have been following the fox farm feeding schedule and i was just wondering it says to feed it grow big along with open sesame while watering with no nutrients every other watering.

can i add the open sesame and the grow big/tiger bloom in the same gallon or do i keep them separate so far iv been feeding it the grow big then the open sesame and then plain water then repeat. is this right or can i add them together without burning it?
