I'm new at this and I feel like I have a few problems with a couple plants. But for now I would like to know why I have plants that are so much shorter then the others
Are they from seed or clones. It's probably like str8 said. If its seeds then it's phenos. But could be multiple reasons. Not am issue at all. At most you may need to end up elevating the shot plants.
So these are clones of the same plant?
How long have you had them?
What kind of Soil,nutes?
What's your temp,humidity?
Take a couple of good pictures of the problematic plants by themselves.
What's your watering schedule like?
STR8
Dam not much leafs lower them lights or raise them pots with T5 you should have short stocky plants tie tops down every couple of days bending them more down
They're clones from the same plant. I've had them about a month. Temp is around 75f - 79f and humidity is around 70% and 75%. I feed them every 3 days with about half a liter each (the pots won't hold more then that).

Looks like over feeding to me. I've had a couple get funky like that when I was running them to high. I think running to much calmag had one of mine looking like that last pic of yours
