Looks like they are off to a great start budolskie. Does the caramel start smelling anything like caramel too or is it just the taste?
Update, week 6 or so:

Plant in front right corner and left in the back are clones from a different one than the other 6. Hadn't labelled them so wasn't sure until recently, these two don't foxtail and have slightly more dense structure and darker smell. It's also ready a bit sooner (the 8 week pheno sort of speak) and the large fans are starting to yellow a bit. Still on 480-ish ppm. Currently on 490, feeling bold today
The row of 3 plants in the front tube are spread out over a larger surface and that is noticeable, buds in the back are clearly more dense.
More height was the main reason I build a new closet, though my old was 3x4 now 4x4. In my setup the tubes are above the rez, which combined take up about 25" in height already. Using a slightly lower reservoir than previously to gain some space, got plenty now. A clear advantage of hydro is that it's easy to veg fast, but that also means more vegging during transition, so plants tend to get taller. I would go with 4 plants on 3x3, max 5 (one in middle). Most important is keeping the rez cool. That's also the downside imo, I need to run a chiller several times a day to keep the temps low.
And thanks Dankster
Had about 7 weeks 12/12 now.

Cannalope Haze pheno #1, this could be referred to as the 8week pheno. 2 plants in the back on the left, and 1 on the front right. Basically all the lower and more compact buds in the field.

And the more haze and foxtail structured bud of the other pheno that will need a week or two longer, still busy spawning fresh pistils and expanding in all directions:

Still on 460-500 PPM. Burned tips are from pushing the pk ratio too high and not the overall ppm.
