Gotta be careful with overfertilization, with organic inputs that break down overtime.
it's easier with salts/High frequency fertigation, rockwool/coco medias.
Easier when the grow is setup with more control at the rootzone.
"Easier" to reset the substrates E.C, compared to organics.
Eventually, the plant will use the media nutrient input, and then their reserves, and then "fade".
(The plant WANTS to reach Senescence, live its life cycle, reproduce and die when its done flowering, of course, if it's a photoperiod the light schedule dictates, but the "instinct" Is still there.)
This is timed with how developed the buds are.
