Leaves turning yellow/purple? Healthy?

[Streetdoctor3]

Wonder if this is normal I’m in week 5 of flower and I just changed the temperature to 78 lights on and 66 lights off in degrees F. The leaves are turning yellowish purple now is that normal? The thermostat before that was alwyas set at around 78 I am now setting a schedule to have temp go to 66 when lights are off because I herd that’s how you get color to come out.

also does anyone have advice for me on my grow room temperatures for bloom lights on and off? Running DE 1000W and co2 1000-1200 PPM should I keep the thermostat at a constant temp? Run it colder at night? What temp should I run bloom at?

Its a bit too cold. Are you under led?

Should try and keep.it warmer that 75 this early on. Also... keep your res warm... cold water can do this too

Oh... wan you want the color to come in when its ready.. not before. The colour change stops the leaves from photosynthesis

so I should keep the temp over 75 during lights off too? I’m using 1000W DE hps I’ve just been reading around and it says that during flower temperature when lights are on and lights off should be about 10 degrees difference. And when I water the water is around 72 degrees

Also when would you recommend temp changes then? Or keep it warmer than 75 all the way through flowering?

do you have any advice for me to keeping temperatures for my grow room? From beginning of bloom to end of bloom? Lights on and lights off temperatures double ended HID lights I think I am having difficulties with dialing in my temperatures for my indoor grow room. I am running co2 also@1000-1200 ppm

Yeh I did read this and a bunch of other blogs; that’s why I set my temps at 78 during lights on and 66 lights off. But seems to be turning my leaves purple which in not sure if it’s good for the plant.
