Well week 5 is almost done and the buds are starting to swell up nicely and are already very dense and solid little nugs. Trichome production is coming along nicely and the tips of the pistols are starting to all turn red/orange. I'm not sure how many week strain Bubba Kush is but I read on Thseeds website that Sage N sour has a 9 week flower. The SnS nugs are a little bigger but the BK are more dense just a little smaller. I'm guessing they need at least 3 weeks more, if not four. I'm not going for a couch lock effect so I'll probably harvest when I have a 10% amber ratio.

On a side note, I had to flush the plants a week ago due to very high ppm runoff on a few plants, plus they hadn't been feed plain water for far too long. Only half the plants were yellowing in the fan leaves, but I flushed all the plants. The ones that were yellowing now look to be yellowing even more. The 4 bigger plants were nice and green but one has started to show some weird wilting and the tips are brown but not dry and crispy??? I wonder if I flushed out all the nutes and they started feeding on themselves? Is it okay for fan leaves to start to turn yellow in week 6 of flower? The 4 that are yellowing are still really heavy and will need a few more days to dry before feeding but the big 4 got feed today. I wonder if the Co2 has any part in the smaller plants that are yellowing. Perhaps the bigger plants are able to take the co2 and the nutrients but its too much for the smaller plants. Would it be wise to mix up 2 different strength of nutes and use a lower ppm on the yellowing plants? The bud leaves are dark green and buds are forming nice just nit as big as the other plants.
