Yeah thanks for this just never had them droop before ! Yes always do my best to keep the coco from going dry.... the pre-lights-out droops are a fairly common response,.. I get this on some of my outdoor photo's too! Well before sunset, they "relax" the leaves' postures,..... As for coco, never even let it get even close to dry, coco is not true soil, and doesn't react like it does either,... should be moist at all times, and with 15-20% run-off every time you feed,.. it's odd CEC characteristics are why it's treated differently than soil, or even peat-based soilless,...
