Is there any reason to not switch from an organic fertilizer over to Jack’s 321 at 4 weeks of flower?
And if it’s fine to do; is there anything I should do differently?

None whatsoever my coco is front loaded with organic nutrients and microbes and i start using jacks day 1 because i believe the microbes actually break down the hydro nutes to make them available faster then in inert oh but just remember last 1-2 weeks to just give plain water to clean them out( flushes aren’t necessary)
