How come my plant is so short?

This is my first grow and my plant is 2 weeks old and are just under 2in, i currently have it on RO original and feed only with ph'ed water once a day. I have it in my backyard, i noticed some white tiny spots on a leave somedays ago but i didnt see any pest. Also no new white spots have appeared since then. Could it be a disease causing all this?? If so wat can it be and how can i take care of it

She's fine. What is the strain? Time to get her out of the cup.

transplant them into there final pots and you will see them shoot off like a rocket.. they need root space..

Dude i dont know why you made 2 of the same post? https://www.rollitup.org/marijuana-plant-problems/647027-why-my-plant-so-short.html
its just stupid if you ask me, next time try and make 1 post instead of making 2 it makes things difficult and confusing.
