RQS - Northern Light & Purple Queen

I FIM'd them a few days ago and seem to be recovering well, I think that was probably a mistake in such a narrow and tall tent but theres no going back now! I'm only having to water them around once a week as they are in such large pots, but over-watering doesn't seem to be much of an issue in these pots with coco coir. I watered them last week at half strength nutrients and this week three quarter strength. I'm not sure what to do when they reach the walls of the tent, is it best to trim those leaves / remove them or do you just leave it? Cheers
