I'm using rock nutrients

Also my first grow

How old are they now?

I would say 5 to 6 weeks i got them they were 4 to 5 in tall i lst trained em a bit

Ok, you really need to take some better pics...side shots...that way we could see dimensions a bit more clearly and also help you diagnose the leaf issue you described. Also, it looks like you are doing one in soil and the other DWC?

Yes that is correct I will take some better pics in a second yes ones in soil other 3 in Hydro they have been same size am I tripping or are they good size

Basically some
Dried
Leaves it's not letting me upload any more photos

???

Hmmm as for the leaf issue...I would likely start here:

As for the size...I have not seen the full plants at all...just the tops and stem root. But from what I can tell the growth is stunted. As to what is causing the slow growth...much more info is needed. Also, for me personally I have only ever grown in soil. So, for the DWC plants I would consult a DWC grower. Now, the one in soil, does she look any different form the others? Does she have the same size and leaf issues? What soil are you using? Have you given her any nutes? What is your light source, how far from the plants is it? What are the temps, rh, ph, etcetera.
