Hey Eggs, I take the Cannatonic at 8 weeks, once she decides to finish it happens quick. Everyone's environment is different so it isn't going to be the same for everyone but I take the Bubba Hash at 63-70 days (usually 63). When Bubba is cranking for me she will drink a gallon and a half every 3 days (in a 10). She'll slow to about every 5-6 days when done. I try to let her dry right up before I chop. The last harvest she went about 10 days without a watering before I chopped. I'd guess yours looks like it may be overwatered. I don't know if you can pick up the pot and tilt it to see if any water drains out. I'd try that then just let her go. 7 weeks is too early to take it though. Everything else is looking just fine.
