Rubber looking leaves????

Ok so this is my first time on this forum and I REALLY need some help!!!!

About 5/15 plants are growing way slower than the rest of them and have very skinny stems with few leaves and the new leaves coming up look all rubber and small looking...any ideas anyone!!!

pics would help

yeah, pictures are useful.

you can't really expect an answer to that!! Give more info soil mix, fert, pH of water, how often do you water, how often do you fertilize, what lights/ how close/what spectrum, how old are they....

Sounds like you might be growing two (or more) different strains?

I will either get a charger today or 2morrow for my digi...then ill post back up..Thanks

Are they in pot's or in the ground?

pics??????

I'm wondering if they are deformed from too much nutes - like I've seen SuperThrive over-use leaf deformities in some of my other garden plants, not the cannabis. (maybe adviseable not to give nutes while high )

pics? pics? you got any picks? ha, jk but really we need pics.
