Yup, I have the most issues in the greenhouse with high temps.Keep in mind that there isn't really any Ruderalis left in modern autoflowers. All that's left is the autoflowering trait that's been diluted to way WAY less than 1% of the overall DNA.
The indica varieties grow in the mountains of Afghanistan and India, they are pretty well suited to cool temps. I've never had an issue with mid 60s bothering my plants. In fact, ive probably grown my best plants on the lower edge of the temp range.
