What does temp. drop do? For blueryder strain...purplemaxx / snowstorm

Tryin to sift thru the madness...lol and some say a drop in temp. during late flowering stage makes leaves turn blue/purple - anyone know if this does work and what temp. works best - and if it works with this strain? Am also using purple max/snow storm during last 3 weeks. Blueryder strain to be exact. Go Green.

not sure about that strain , but i have purple power and by lowering the temps over night slowly over a few a weeks turns the bud purple , also by changing the ph in the soil whilst your flowering some strains can do the same thing

Hmmm, I've gonna start dropping the temps a bit at night then. Hopefully that and purple maxx might have an affect. Thx for the reply.
