I'd like to see though do you use a trellis, how long do you veg, and what's your average yield per light?
Jack, do you move your lights to stay a certain distance from the plants as they go thru stretch or keep them at a fixed point the entire run? Do you feel that they stretch less if the light source is closer to the canopy?

At the end of the day the all the base nutes work good with Aptus if I was in pots I would rock Heavy 16 , But since where in beds CANA COCO is easier to flush every one is worrying way to much about base any good base nute will work and each grow is different look at how many guys love Pure Blend Pro, I have not had such good luck with it but im willing to give it another try.
