Two week old seedlings have clawed leaves and are not growing at all. Have checked the root system is good. I used straight tap water for the first week. Now I have pH water and top dressed with worm castings. Growing in straight Coco coir and perlite.
Never give plain water to coco........it messes up the cation exchange capacity. I highly suggest feeding with salts instead of that top dressing stuff. 2 weeks from sprout........grown in coco/perlite..........fed daily, for a comparison.
