Hi Cultivator. I am as hoping to get some help. I am near the end of my grow and would very much like your opinion on when to start flushing. I have done a lot of research on several different sites and the information is very conflicting. First of all let me give you some background I am growing Critical. Northern lights and bubble gum. The soil is fox farms ocean forest with 30% perilite. The nutrients are fox farms trio and their soluables. I pH my water and feed only every other watering. The plants are in 5 gallon pots and I give them a gallon each every watering which is generally every three to four days whenever the pot is dry. I am not impressed with the yeild and I don't want to sacrifice any more yield by flushing to soon. I have already started to flush my Northern Lights and am now second guessing myself. I would appreciate your advice and critique. Please be honest I am trying to learn and not looking for a pat on the back. My journal is Killian's First Grow.
