Quick update. The difference between this week and last isn't really that much. They are swelling noticeably, but I don't think this will be a massive crop I was hoping for. The plant on the left in the rear seems to be a lot further along than the others. The top leaves are crispy around the edges and almost all the hairs have turned brown. The other three plants have lots of white hairs left. I'm really struggling to keep the PH above 5.5 on the tallest plant and have started adjusting the PH to 6.2. If I adjust to 5.8 it's down below 5.5 within 12 hours. To my eye none the trichomes on any of the plants are cloudy yet.
