This is probably the phenotype of the weed. Waiting to harvest later can also affect it but there are many aspect of cannabis cannabinoids that we don't fully understand yet. for example I have made tinctures out of a LSD plant and a Mexican Airlines plant and each one gave me a different type of high. I loved the LSD plant and disliked the Mexican airlines one a lot. They where both high THC and normally I don't like high THC.
You grew these plants out in flower for 10 weeks and that should have been enough time for them to ripen up. However your diary updates are incomplete and it will not load any photos for me from flower week 5 through 7. So it could have been harvested early if the weeks in your diary are not accurate but they are I don't think it was to early.
Best to try out some other indica strains, as they tend to be more compact and sedative in terms of the high but not always. just have to shop aorund.
Best Of Luck!
