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.
sarah louise Reviewed by sarah louise on . My leaves are turning purple!?! 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? Rating: 5
