Just a quick update, here's what I ended up doing...
I supercropped 4 of the tallest side branches that were too close to the light, here's a couple pics right after (Fri night).
And a pic from yesterday showing these tops growing upwards again.
As for the main cola, I couldn't bring myself to snap it lol... So I managed to rig up one of my COB's to give it coverage.
You can see the top has grown another few inches since Friday (only 10" from the top of my tent now)... think she's pretty much done now though (hopefully lol). Time for her to pack on the weight
