I dont care how long you say you have been at it,you should know that inside grass needs to be flushed if your that old.
I'm familiar with the reasoning to flush chemical supplements from hydro, indoor soiless efforts and must exclude organic grows from your indoor generalization. While it may be difficult for some to understand, the only visable difference between outdoor and indoor growing is general confinement for indoor growing. Not too many one pounders grown indoors.
Indoor organic container growing isn't that much different from outdoor in-ground or container growing. Grow medium, light and water. If the grow medium is prepared in a manner that sustains an annual flowering plant throughout its brief life cycle, providing adequate water and dealing with nature's threats are the only outdoor chores until harvest. Why would anyone flush a grow medium providing that peace of mind?
I'm attracted to the extra effort to grow the finest buds I can. That's the reason I'm doing AACT teas to supplement microbe activity in my grow medium. Microbes deliver processed decomposed nutrients to the plants in exchange for carbon. Before becoming hooked on current organic growing techniques I successfully grew organically but my 'extra' was molasses during the flower cycle.
Do what you want but I have to question why anyone would want to follow a feeding schedule that exists only to devour time and money when more efficient options are available. There are posters on every grow forum who grow organic weed indoors, but they're far outnumbered by growers who have limited knowledge of what actually transpires between the grow medium, sun and water. There are so many companies vying for that easy money that organics are a minor market share. But rapidly growing share as organics bring top dollar in any internal consumption market.
My first indoor grow was in a San Francisco basement. Dirt, baked in the oven at 400° for 30 minutes mixed with steer manure was the grow medium, florescent lights and paranoia. Crummy weed by today's standards, but far superior to buying three fingers of Mexican brick weed and I didn't hang with the music crowd that took everything Mendocino could produce. Thanks to science, people have learned the earth is not flat.
