I've been keeping the lights on 15/9 schedule for 5 weeks. Is it ok if I put them on a 24/0 schedule just for the last week of veg before I start flowering (12/12), or will it harm or slow the flowering cycle in any way? The reason is just that I would like to try to make them grow as much as they can before flowering.
Yes, but can I give the plants more light during the last week of veg or will it disturb them in some way later during flowering?
