They may look little now,but in Time,key here is time,they will grow rapidly.
I think they look good.I remember my first grow,nervous about everything I did.Have fun and don't be afraid to try things,marijuana plants are quite resilient.Sometimes you will get a runt,and I don't care what you do to it,it will just stay a runt but runts are just as potent.Happy Growing,I do have one suggestion though,I used Grow Big for awhile,until I used ff kanga roots,that stuff makes them jump like nothing I have ever seen.
