Auto in flower tent

I currently have one Pineapple Express auto by Barney’s farm in a tent with 3 other blue cheese aka blue widow plants by canuk . The tent is only 5 ft tall so I have height restrictions with my plants , will the autoflower flower fine once I flip to 12/12 and/or should I let it go longer once flipped . I plan on vegging for another 4/5 weeks which would put the auto at 8 week (almost done hopefully) I’m just wondering about the end of the cycle if anyone has experience please let me know what you think

I mixed an auto into my flower room. I found it to be a mistake as the 12/12 schedule diminished my yield substantially, also it might stretch faster then the photos and shade the lowers
