Day 72
Day 72:
Coming along quite nicely. The flowers seem to mostly be done stacking and are now starting to get nice and fat. Resin production seems to have really ramped up in the last week, the smell is loud and the trichs are really plumping up.
I dropped the canna A/B and PK completely, just using calmag, cannazyme, boost, Rhizo and some molasses every few waterings. She is starting to get a little fade and might be done a little sooner than I originally thought, maybe by day 85ish.
For the last year or so I have been experimenting with light spectrum, to the limited extent my Sun System CMH will allow. I start the cycle with the 4200k bulb. When budlets form I switch to the 3000k bulb. When most of the flower formation is complete, 2-3 weeks before harvest, I swap back to the 4200k bulb. It’s generally accepted to give plants more blue light during veg, but I don’t see much talk about shifting back towards blue at the end of the cycle. This is naturally what happens to plants outside as the angle of the sun becomes greater and the light passes through more atmosphere reducing the intensity and also filtering out more of the red light. This reduction in DLI and the shift towards a bluer light spectrum help to signal to the plant that the season is coming to an end. I have also noticed that if I continue to give the plant the same DLI into late flowering that it causes foxtails in most strains. Starting with the stretch and through to late flower I keep the DLI at between 60-70. As soon as the flower stacking slows down I swap back to the 4200k bulb and start backing off the DLI to about 35 for the last couple of weeks. Since I have been doing this I believe I have been getting better terpenoid development than when I finished them under the 3000k bulb. This cycle I will be using a Growers Choice 10000k CMH finishing bulb for the first time, it produces the most intense blue light I have ever seen. No idea if they really work, but the bulb was not that expensive, and I have wanted to try one for a while. I will only use it for the last 2-3 days.
