First Time Grower, Outdoor CBD 'Suzy Q' in pots: when to harvest?

Hi all, long time lurker, first time poster. First time grower, too.

I have 2 Suzy Q clones in 10 gallon pots on my sunny patio in San Francisco. Extra sunny during this 100 degree heatwave...

I haven't found a lot on info online about growing high CBD low THC plants, other than to harvest a week or two "earlier than normal" for maximum CBD. Nothing Suzy Q specific at all. The folks next door have some Sour Diesel in the ground and some type of indica in a pot. My Suzy's look further along than his SD and less so than the indica.

Does anyone have any clues about this? The nursery said 10 week flower, so that is my current plan unless I learn something new.

100 degree heat Will get you some fluffy airy buds. Also for cbd it's actually the opposite, harvest later then usual that's when the thc starts to break down and convert into cbd
