Just read through the thread Beer, looks awesome. You're doing a great job. It could be up to 2 weeks or it could be 1, you'll just have to keep your eyes open. At this point I don't think lack of nutrients is going to have any major affect on them, although it may slow there progress a tiny bit due to shock. If you want to you could probably give them a low dose of blackstrap molasses to supply nutrients for a day and then start to flush again, but I think you could probably wait it out. For couchlock I wouldn't let any more than 75% of the trichs to get amber because all the ones that were amber first start to deteriorate and decrease in THC and we don't want that. Good luck and keep us posted.
