Pruning auto flowers

[djgraw 0]

My auto flowers are starting to get a little tall. Is it ok to prune the tops?

Welcome to the forum mate,

This plant looks fantastic how do you use mother plant? I tried DWC for a few years, but the weather in my city is very cold in winter and started having problems ... now use coconut fiber, with better results.

Regards!

You can top an auto, but do not expect the trimmings to clone very well; theoretically, even the clones are on the same flowering time-clock as the mother-plant. 

If you must top an auto, it is better to do so before pre-flowering.  The earlier the better, to allow the plant to recover and produce ample vegetation to support the upcoming flowering.
