Leaves weird color

I first notice this last week. I am half way through flowering and have no idea what the leaves being this color means. Maybe heat stress?

Any help would be greatly appreciated

Thank you

What color are they? Pink? Purple? Blue? Orange?

Give us a little more info and you might get some help.

How many weeks into flower? What's the harvest time on your plants? What's your ph? What have you been feeding them?
