Do not feed,,, Fox farm has plenty of nutes for at least 4 weeks,, listen to the @gravekat303 the wise one. no need to feed fox farm soil for at least 1 month of veg,, then lightly top dress with the rainbow or light liquid food.. (one or the other) no need to do both at the same time… but i would just water with hygrozime and calmag once a week until her lower leaves tell you to add stronger dose of food.. fox farm comes already loaded. water and hygrozime is perfect at start of veg, or at the beginning of any repot..
