Well shit. I threw down a 3 plant 600 watt scrog. 2 Double Bubble and a Choc D. The Choc D was never a mom. I put it in at 10 inches, used most of the stretch to fill any remaining holes, and it's still stretching week 3. I'll supercrop if it gets much taller. The Double stretches 75% or so, while the Choc will stretch 500%+ (see profile pic).
Anyways, I like the way I've been feeding in coco, and each yield's gotten much better. I got rid of tons of sucker branches, so I'll have bigger easier colas to trim.
First pic is just cool . Top strength feedin @1.3 EC, and never go to runoff. With Drip Clean, and just enough food, the plants are using most of the nutes, so little salt build-up, plus I give em a good long flush.
