desertdan, Can (or have) You 'sampled' a small bud, to see how it's developing? The high temps can cause stress and fox tailing. A friend of Mine had heat problems in His garden (Brussels sprouts, not cannabis) and 'fixed' it by making a tent out of cheese cloth over the plants with a small mister hose along the ridge. The cheese cloth cut down on the direct amount of sun light and the evaporation cooled the plants. I do not know if You can set up something similar for Your plants, but it's a thought.
