Purple jazz not purple

How come it’s not showing any purple first time growing

[Northcountryguy]

Somebody Will be along with the technical answer, but bottom line, whether colors show at all, or how brightly, has to do with genetic expression, stresses, and so on. The colors on the strain description of any strain are only potential, not guaranteed.

I get purples when i drop the temps at dark in flower i also add ice chips to the soil in the “dawn” for them …

Yes. It’s called the “Cold Shock” technique.
Right at lights out, 7-10 days before harvest, water each watering with ice water and dump some crushed ice on the soil. Makes-’em turn purple in a week! I tried it last grow. It works!
