Hi
@TheCode! Well it's really hard to over-water with a fresh and airy coco, since this medium will immediately get rid of its excess of water, unless 100% of your waterings are very heavy you shouldn't see signs of overwatering. Is there a chance you re-used the coco from a previous run? In my opinion your plants do suffer from a not-acidic-enough pH (in coco 5.8 is your sweetspot), probably a bad airflow, and not enough Nitrogen during the vegetative stage (plants are slightly yellow). In this situation I would: 1/ help the container to dry faster to make sure over-watering is not the source of your problems, a tiny fan blowing a continuous breeze onto the container's surface should suffice. 2/ help the plants to handle the stretch by giving it a bit more of Nitrogen, for the very last time. 3/ lower the pH to 5.5-5.8 for the entire blooming cycle and 4/ make sure they have a cool breeze all day long and double check the airflow all around the plants. Hope this will help, keep us updated and happy growing!
