Day 68 for Grandaddy Black. She has clearly reached the very end of the soil nutrients and so the nitrogen deficiency yellowing will come soon and fast. I’ll be applying food as soon as it dries out. I’m topping left and right as I try to delay the height. One more week until the flowering flip ... I think I can make it. Lots of work this week as I proactively treated for pests with Safer’s potassium based soap and neem oil. I’ve learned you can’t be too careful. My server was down with my temperature/humidity data but the manual readings greatly vary depending on location. Because the canopy is so thick, the undercanopy is as low as 20 degrees Celsius. The temperature is as high as 25-28 degrees Celsius at light level. Daytime environment will continue to shift as my furnace runs and winter nears.
