Autoflower concerns.

Good day folks! I've got an auto flower femanized White Widow who's just now beginnings to flower. I've got a bag seed and a femanized Strawberry Cough that are ready for the change to 12/12. The White Widow, Strawberry Cough, and the bag seed all are on a 18/6. My question and concern is will switching over to a 12/12 be too detremental to the auto flower strain? I'll throw some pictures up here shortly for sharing sake.

12/12 will be fine, just don't expect the same growth rate, will be slower but will still finish.

That's kinda what I thought. I had originally intended to isolate the auto and keep it on the 18/6 but due to space and budget concerns with lighting that's not as possible as originally thought. Thanks for the input sir!

Here are the femanized auto white widows. If I'm not mistaken they're just now beginning to flower.

This is another picture of the same plant showing what I believe was light burn as the plant shot up onto the light outta nowhere which I've since remedied. Any input, once again, is appreciated!

Edit: just saw the pic is stupid blurry there in the middle but you can see a little damage on the leaves- I'll try for a better image shortly if I can get it in before the timer clicks lol.

Updated images. Hopefuly better than the last showing possible light burn on my autos.

Your autos look very stretchy, how close was your light for it to burn?
