The Northern express is still showing signs of heat stress, I have my lights set around 28" from the tops now so hopefully this starts to turn around. It's the same height and stature as the other three plants that started at the same time, looks healthy enough despite the leaf curl. Guess we'll wait and see how this one goes.
@Lou_Grows, I do.. smell and taste. I've never done a true side by side comparison. But I have grown the same strain twice... once with, once without and there was a definite difference. I've used Terpinator in over fifteen grows and plan to keep using it. You should give it a try for yourself.
@Tazard, I yanked the lights up another couple inches in there. They are now at about 28". Hopefully this can straighten itself out and get back on track.
