Every watering All water used for the girls.You add humic every watering? and no kelp? I do both once a week in both setups
I try to refrain of adding 'nutes' to my rez water. I add Thorvin kelp to my compost tea mix and use that when I top dress or if I have to add liquid nutes in flower. I use the tea for my water when adding the needed nutes and top water spraying AFTER a dry period. Spray in cycles to let it soak in slowly without flushing any nutes into the rez. I usually wait 12hrs or so before filling the rez to give it time to soak up any I might have washed in the rez.
Note: I don't consider various ferments as 'nutes'.....some ferments yes. J, FPJ and the fish ferment......I'm high AF and can't remember the acronym....... I consider nutes. I would only add them to the rez as a last resort if the plant was in trouble. And only what it was drinking in 24hrs
I have other ferments that I do use in the rez. EM1, fermented insect frass, for immune response, ferments alfalfa......borderline nute in my mind.
I consider it a 'nute' if it has a direct nutritional value to the plant and not mainly an enhancement of/supportive to the micro-biome.
It is possible to 'burn' your EB girl if you have a too high nute content in the rez and you have the VPD dialed up with her raging in stretch. She's been relying on that clean water in the rez for a large part of the make up for VPD driven transpiration. She has to take up the water and the nutes come along.
'Nutes' in the rez can start an out of hand microbe bloom, when that happens, the feeding causes a rapid pH drop and will quickly kill your girl if not caught quick enough.
I try to base that on science. That above post is why I just love this method!
I gotta get a little more 'adjusted'. Got a GTA playlist to do wif muh crew in 30!
