I’ve done more reading about than growing (3 crops, I think) with coco and it seems the general consensus is to water and fert to runoff every day, and in the later stages, even twice a day or more. The stuff has to be kept wet. I’m about 2 weeks away from harvest (but not anything like your monsters!) and I’m watering twice a day. Seems this is the only disadvantage to using coco, the ferts get used up faster than with soil, which should dry out somewhat between watering. Good luck, Alan, you’ve got some beauteous plants going!
