Plant turning purple in direct light

I'm growing a bubba kush it's turning purple nicely at the top but everything under the light canopy is not purple? Obviously it's the light? They also have a month left to go could the lower change to purple by then?

What sort of light's are you using and what is the light penetration to the lower leaves?

"..it's turning purple nicely " .."..Obviously it's the light?"

See the purple as jammed up plant blood(Xylem)

that has stalled because of your inability to maintain correct temps

less red does mean more growth

keep your temps up and grow that plant

see it like bruise in humans

good luck

It's not "light" or "lighting"...

V? Ignore him...

Temp swing's at night, won't hurt you,, if you keep the root system swinging no more then 15 F.
High K use can bring out coloring.

Bubba - Good bubba, can and does purple like you say your getting anyway.

Not a problem, so don't sweat it!

6 million dollar question....

Water stress, wind stress, nutrient stress, temp stress, take your pick!
