Next time you grow fill the fabric pots with your medium only. Under the pots, on the trays put a layer of pebbles (marble, lava rock etc) so the pot drains without reabsorbing the run off. What runs off should stay off, it is unnecessary and it follows the only way it should follow. Plants have their way to keep what they need from the medium and the medium can only absorb a certain amount of water but needs the run off to get rid of many salts that are only a source of toxicity. Coco is unforgiving compared to soil in such an event.
If you want to mix Coco with a soil, prefer the scenario where soil is the main ingredient and not coco, 25% Coco is the maximum you can have. Soil is more forgiving and provides a buffer for nutrient problems, Coco is more manageable when it comes to flushing and overwatering but cannot be treated as soil since it's buffer properties are almost zero.
Also if you SCROG then lollipoping and defoliation are part of your every day routine along and equal to/with spreading the canopy on the trellis. That goes for both indoors and outdoors, since SCROG is a traditional style of grow for many outdoor crops not only cannabis, all of them involving heavy pruning activity. You need air to create many bud sites (smaller than a single large one but with bigger yield overall, quantity is a quality in itself) and also to avoid mould and rotting issues.
