PH fluctuations happen in the reservoir, but not in the coco coir. If it's a lockout it could be from build up of salts from the nutes in the coir. This happens sometimes from not watering enough to runoff. Check the PH coming out the bottom of its off from what is going in.....keep watering until it matches. Coir is inert absolutely no chemicals so what goes in comes right out as it should with a 20% runoff every feed
