slow seedling growth in coco

this is my seedlings at 5 day of sprout ive grown in soil and they were much bigger in five days ive been watering with advance nutrients voodoo juice and superthrive 5.8-5.9 ph should I add light dose of sensi grow?

Had the same shit trying out coco recently. More nutes won't really help, get some GHE Mineral Magic and sprinkle round the base, and get some cal/mag if you don't have it already and add to your waterings/feedings. Also make sure that you've got some proper runoff after watering don't add little bits, a lot at once and then big breaks.

Not diggin' the coco myself, switching back to Hydroton as we speak.

Chill on nutes, try to move the light closer. Coco is slow going off the bat.

Is coco better for clones?
