Hey Shazzabee, first of all, don't panic! We've all been there with the multi-strain struggle, but having that second tent is a total game-changer for finishing them off individually. Looking at your photos, you are definitely in the home stretch. That yellowing and leaf drop you're seeing is actually a very normal part of the "senescence" phase, where the plant focuses all its remaining energy on the buds rather than the fan leaves. Some of those girls look like they are already starting their natural fade, especially with those darker/purplish tints coming through. Since you're worried about your flip date, stop looking at the calendar and start looking at the trichomes with a loupe; you want to see mostly milky white with a splash of amber before you start that final flush. If one strain is fading faster, move it to your other tent to begin the flush with plain water while the others keep feeding. You're doing great, and the harvest is going to be worth the stress!
