Cool line-up, looking good so far. I'm subbing up for this one. I have also noticed sometimes when they're growing really quickly they will turn lime green and look a bit sickly. I usually up the nutes a little to compensate and eventually the color catches up with them.
I think you will be in for a treat with the CBD Kush, it's my favorite strain at the moment. It smells like fruity candy and the high is really smooth and relaxing. It's a bit less potent than other strains obviously but that also makes for a functional yet relaxing high.
I'm also planning to drop a CBD Skunkhaze bean in the next few days.
Man, those mad dragons are making a dash for it. It's interesting to see how different strains grow under similar conditions.
