Early pistils? And drastic height difference.

Hello good people!

I need some advice!

This is my first grow and I had a bit of a hiccup earlier on, I biffed it and tried to use some fertilizer (but I’m using soil... dummy) and the first time it was a bit of an experiment so I only did it on one of my three babies and it worked! It started growing faster than the others! So next time.. I tried it on all of them.

and gave all my plants nutrient burn (to the best of my knowledge). I also had a fan pointed at them making them curl. So I did some digging and turned off the fan. I flushed the plants an they recovered.... kinda.

the first one is back to growing fast but the other two are a little stumped.

currently, the lights are still on a 18 hour schedule, but all three of the plants have already started growing pistils.

the seeds are supposed to be a blueberry CBD hybrid.

I am not going to ask ‘why did this happen?’ Because I know I do not have enough variables (though I’m open to your theories) but I want to know what you think my best course of action is now. Do I just switch the light schedule to 12/12? And take the L? Or are they technically still in veg and should I wait for the 2 littles to catch up a bit and just prune the big boi if I need to? Are pistils growing during a long light cycle normal? Or is it due to stress? I read that it just means the plant is mature, I just want some affirmation. Could it be an auto flowering trait? Since it is a hybrid?

Thank you for your time and brain power!

Btw the temp is max 85 min 70
And humidity is max 89% min 32 %
Hovering around 50 %
While not running the fan

Also these were germinated around April 19th

I hate to say it, but I'd just start over if I were you. Flowering those will yield next to nothing, but something is seriously off if you've been begging those for over two months. The three smaller plants in the picture below were planted on June 11 for reference, and have been under nothing more than a fluorescent tube lamp until today:

Thats not to say they won't keep growing on 18/6, it just may actually be quicker to start fresh. You need to figure out what went wrong so you don't repeat your mistakes.

Next ... more details. What light? What soil? What nutes? Did you only feed the one time an then never again after they got burnt? The more details the better.
