Sorry, been offline for a while.
If there is a light leak or timer mixup (as it appears), you're watching them reveg as others have mentioned. If the timer was the issue (rather than light leaking through the vent ports which is the most likely place) and you've sent them back into flower, the entire process mostly starts from scratch, so they should finish in about the same number of days as they would have originally, but starting with a new flip date.
Sounds like they're going through stretch again, as expected.
