Something slowed GGs down...my best guess is that lack of calmag suplement is an issue.
CBD crack seems to be effected the least.
I hope they will start some rapid growth and intake more nutes.
I'm on week 8 of my GG. Calmag definitely helped mine out. Started getting brown spots on leaves and the calmag put a stop to it. I mix in 2 tsp per gallon with the rest of the nutes. Good luck!
