My leaves are turning purple!?!

[Steelwool]

These pictures were taken a week ago. They've been flowering for 6 weeks. They are "Pot Of Gold". This week the larger, older leaves started to turn purple. The trics haven't started to turn amber yet. Should I start to flush now?

what are the temps?

[Steelwool]

They got pretty cold like lower 50s in the dark cycle and upper 60s lower 70s in the light but only for a couple of days over the weekend. I've cranked up the heater and it's gotten warmer outside so it's been corrected. I thought the cold caused things to go light green, at least in veg and early flower? I'll take a picture or two tonight and post em.

The purpling is a normal response to the low o/nite temps.

Large swings between day and night temps can cause the new growth to look light green (cold bleaching).

If you have warmed things up you shouldn't have anything to worry about.

I am facing cold temps such as mid to low 50's aswell when lights are out and I'm prepared for the purple leaves. Im pretty sure it doesn't have a negative affect on yield?

it shouldn't hurt yield its just a sign that your temps are dipping a little at night, and personally i love it when things turn purple i think its pretty

It will depend on whether the temperature is just dipping down for a short while during the night or whether the temp dips after the lights go out and stay low for most of the night.

The second scenario will most definitely impede flowering.

The second scenario will most definitely impede flowering.

Does it slower the process or does it actually reduce the amount of floweR?
