Your photoperid plants look fine, as for ur autos there is something seriously wrong, first I would like to know who sold you the beans, second you made your own mix, it could be a really hot mix, autos have a very delicate root system expesiley when they are sprouts, in my experience a stuck auto is trying to get rid of to much of something, did you try to feed It? And sometimes you get beans that pop and stop, I have seen this, in my opinion your mix may be to hot, 2 your plants are trying to get rid of something, or 3 you got some bunk beans witch happens more than you may think, I just had an auto that was in veg for 60 days before I added some flower base, bloombastic ext, if at 4 weeks your auto should now be in pre flower I would flush the plants out and see, what happens but at this late stage, so what I think it may b is your mix is to hot for an auto, or more likely you got bunk beans, I wish I could do more to help but in my experience that's what's up.
