I was at a loss for this Coco Kleanse - never heard of it. Will likely forget it just as fast. Because I think it is a bad idea - anything that claims to clear all nutrients, including cations will sour my coco. Coco ( to be properly buffered ) needs a surplus (to a degree) of calcium cations.
So if things are slow in coco, you are probably missing a root inoculate. Coco is a sterile medium so every element ( yo, microbes ) needs an invitation. I have used various (
great white, canna rhizotonic ) and get similar results. You can use less once you have the desired root mass. If you are growing in coco and don't see lots of nice white roots, you are doing something... well, wrong.
When you de-pot, take a look at the roots. If they haven't like engaged most of the media, larger pots are not your answer. You got some other thing. A too big of a pot in coco has its own problems.
So, let me assume the roots are puny and not developed. Put it back and feed light with a root inoculate. When it comes to increasing feeding, press the pedal lightly.
