To be fair, those aren't the main buds. I'll take a photo of those in a couple of days when I take my weekly photos.
Everyone always says it's the light bulb, and it makes sense, but I keep changing them every 6 months and the two bulbs I'm currently using are months apart and so far yielding exactly the same as far as the buds are concerned.
It's a vertical 360-degree grow, so area size is irrelevant.
It's gotten a lot colder and I put the plants a few inches farther from the light, so temps are ~27C now.
Now sure how to tell how many weeks this strain needs. I could keep half for an extra two weeks, but the fluctuations in yield between plants is huge, so there's no way to know if it's the extra time or not, and the trichomes could get too far into the amber side..
