Hey friend,
Since you've been back have you checked to see if your timer changed or is off at all by any amount of time? I had my power go out last week in the middle of the night and it set my timer back by about 2 hours, instead of my lights turning out at 11:15 pm they didn't shut off until almost 1 am!
I ask because when a plant goes back to making 3 finger leaves high up on the plant that is a good sign of revegging...usually because of light stress, light changes, environmental issues like high heat, over/under water etc. Usually a reveg plants new 3 fingered leaves have fairly long stems..versus single finger sugar leaves tucked deep into the buds.
I know an autoflower won't truly "reveg" but it's symptoms can be very similar in the way of leaf changes.
I would go through and double check any possible changes that may have happened, then see if you can possibly raise your lights, get the heat back to a comfortable zone and watering back on an even kiel and hopefully she'll just pull right back into good health and flower building.
Happy growing. ✌️
