So to me looks like your PH is low. This will cause the newer growth to be yellow and the old growth to be dark green. I would check your run off. This can cause your buds to be airy and affect the final yield.

Just picked up a PH600 meter. I was using a generic (crappy) pH meter before which told me my soil was slightly alkaline. I just used the PH600 and its reading my runoff at 4.8. Also, I haven't seen any significant growth in buds since it started flowering about a week ago. Anyone have any ideas how I can raise the ph since I'm already in flower? I'm going to be really bummed if this plant dies after all of the time and effort I've put into it.
