Sub Irrigated Hempy w/ Lucas Formula

Barbara is still hanging in there, shes growing slowly. Still struggling to get the pH and EC where I want them but at least they're within acceptable levels and shes not showing any further deficiencies or nute burn. I flush the entire medium with ph'd water containing only calmag every other day until I get the EC down under 1.0 and then I'll go back to maxibloom
