I think they are finally done stretching. I had to get zip ties this week and zip tie my light flat against the top bar. Tallest branches right now are about 16 inches away and center of the canopy is about 20. Although the structure is shit, I think I did well with defoliation and lollipopping. The light is penetrating all the way to the scrog net and the majority of the canopy is within the recommended 18-24 inches from the light. About 90% of all the bud points should be getting the recommended amount of light, so I am pleased with how it turned out. Discovered I had a pH problem this week. My pH has been low, around 5 and I think that is why I have been getting blockages. I have begun to correct the problem slowly watering 2 times around 6.5 and now I will probably water between 6-7 all week to correct for the low pH. They now need to be watered every day so this last month and a half of growing is going to be a pain, but such is life. All told, I am happy with the tent so far, and now that the humidity is much more moderate, I think keeping conditions constant should be a lot easier.
