End of veg plants are looking real bad, lower half of plant leaves are yellowing and dying. See pics.
They're in coco coir with perlite, about 30% coco.
Feeder pump 3 mins on every 4 hours. I thought that interval would give them a good flush of fresh water/nutes.
6 inch gap.
I feel like they are not getting enough drainage and air to the roots. Coco really can hold water. But I figured such a small percent of coco plus the 4 hour interval would help with that. I chose coco because turface is expensive and has to be shipped, but I'll probably have to go back to it. I'm seriously thinking about using hydroton, that stuff will guarantee good drainage. Has anyone tried hydroton
And does anyone know how to test the drainability of a medium (forgot what D9 was calling this), the ability of a medium to drain well.
