I see amber clip a bud leave it out overnight and try it if you like the buzz its ready lol,
OC i'm just going to throw this out there because it helped me when I fill my res I mix nutes in a 5 gallon bucket in this order Silica (Give at least 1 hour for it to dissolve),cal-mag, any other nutrients ,kelp,fish seaweed ect. Grow or bloom, pk boosters, sm90 or wetting agent,hydrogaurd. I noticed a difference right away plants got bigger healthier trunks,stems,color everything better.
at this point in your grow I would do as you said but also add some molasses unsulffered ,it won't depart a taste and yes leaving your plant in the dark is supposed to increase res/tric production, I leave my fans on so no danger of mold I cant tell if it works how would you check that lol
