Blue Gelato is powering along nicely, I topped both plants just after I posted the pics last week, the Blue Gelato has responded amazingly, the Lemon Kish is currently struggling along behind. Blue Gelato is directly under the corn cob LED light whereas the Kush and is under a CFL and so far their is no comparison.
The Kush is looking a little bit runtish in comparison to the BG41, however I'm. Sure once it gets under it's own corn cob LED (over and above the Kingbo LED grow light).
I was considering topping them again, but I reckon that would make it very tight for space.
Still not using nutrients, and if I decide to I'm probably only going to use Tomrite.
