3 finger leaves and claw, stunted flowering. Might be half auto or hermie father

Upper leaves of 2 of my plants are growing 3 finger leaves with claws and they look very unhealthy. These 2 plants are the tallest ones, during flowering stretch their upper leaves grew taller than the hood, so they couldn't get light. Supercrop didn't stop them, they got 6.6 feet so I go vertical and bend and tied them.
After asking google, I learned that re-vegging and heat stress is the most common reason of 3 finger leaves and unfortunately both these two reasons might happen to me. These are supposed to be autoflowers and I always go with 16+8 light schedule. 3 weeks ago they get started to flower under 16+8 but a week later flowering seems stopped. Can autoflowers re-veg by the way?

After switching vertical, the upper part of grow room got hotter because flooded tube pulls air from down and upper parts mostly stays hot. But still the only thing these affected leaves have in common is that they were taller than the hood and didn't get much light.

I also have some doubt that they might be mixture of autoflower and photoperiod. Their mothers were autoflowers that planted outdoor and they were polinated, this is how I get these seeds. All 7 seeds turned out to be female, so I thought one of their mother get hermied. But this stunted flowering made me think that their father might be a photoperiod since autoflowers cannot reveg as far as I know.

So what do you think?

BTW it sounds crazy but their father might be both hermie and photoperiod.
That “ litter “ of seeds will run all over the place because of the cross. It will take at least 5 generations to stabilize.
It is a potent strain and I have more seeds for the next year. Didn't know it was a cross, last year had no problem under 16+8 flowering. I'm planning to switch to 12+12. Any advice?

As to your heat issue near the top of your room, since you moved your cool tube to vertical. Why not just move your ducting to the bottom? Like this-20200915_073320.jpg Even though the middle light has some ducting attached to the top (its bent over like a slinky) it and the light fixture in the foreground are drawing air from the upper part of the room. That should help get some of the excess heat from the upper area of your grow space out. That's what I do when I run a vertical grow anyway.
Good luck friend!

Mind moving some buds out of the way? Hard to see the forest through all those trees.
