Sub Irrigated Hempy w/ Lucas Formula

Had some growing pains this week. Some nutrient burn on the lower leaves so I started adding plain water to dilute the reservoir. The leaves were also clawing as if they were being overwatered, I had an extra line running from an air pump so I attached a small airstone and fed it down the irrigation pipe. Might help, definitely can't hurt. I'm letting her grow until I can top her and get a cutting suitable for cloning then I'll start mainlining or manifolding
