Both plants are very nice. They should put on another 10ish cm over the next 5 days if you hold temps steady. Both will grow nice colas and have some decent side growth. I like to top my autos and I get 5 sets roughly always 60-90cm. And I get 10 colas laden with buds. I know a lot of ppl say you shouldn't top autos. But unless you pull them down and grow them vertical you will always have a top nice cola with lower airy/larfy growth, unless you got a super good light, which you do have so you should be golden, so I hope she fattens up for you all over I only had 100watt leds so growing normal would have given me poor results. They have a very nice shape, your plants!. I'm going to give growing autos the normal way my next run, but I can't see getting more bud, but they do make for nicer pics.
Good luck with the the rest of preflower, you doing a great job, nice nutrient line up. I hope she gets nice and fat after a few weeks of flowering.. happy growing.
