@EGSilver,
My feed goes in at 1.4EC and run off has been 0.8EC so I’m wondering where the extra 0.6EC is going if the plant isn’t up-taking.
Your right in the sense that the Cotyledon has enough for the seedling but that doesn’t mean it won’t eat more if given it.
Growing in a 70/30 coco coir to perlite.
