Are these definitely autos ? I keep having the fear these maybe photoperoidd I've put this exact question up before I'm just anxious

Oh dear heart! Don't worry about what kind of weed you've got! At this point of their growth, there's no difference in how you would treat the plants. With photoperiods, you can do a lot of things to them in veg and extend that veg state as long as you want whereas you can't do that with autoflowers... But from the moment they set flowers, the treatment of them is exactly the same... Relax! You're doing very well with this grow and I applaud you! (And yes they are autos.. photoperiods cannot/will not flower with more than 12 hours of light per day).
