Thats a hard call with no info. Have you watered with any fertilizer and how wet do you keep your soil? They are way too small for nutes and they need to be kept pretty moist for a while and close to a cool light source like flouros or cfls so they dont stretch.
yeh there is pellet fertiliser mixed into the soil, its like a 5 in 1 types of animal poo mix...
also lots of perlite in the mix too, could this affect them?
I water them like 200ml every 2- 3 days
no soluable nutrients just tap water
not sure if it would be over watering but the leaves have gone real dark, so maybe over fert?
how old are these? that might be a lot of early nutrients in the manure mixes for them? they look super young. you need to move them into separate pots like the other posters said.

Hi mate i had this problem before in your first pic it looks to me like you got 7 or 8 plants in a very small area they are probly competing for root space you need to split them up or they can kill each other off i would do it now as it looks like root stress.i maybe wrong but they got to be split up sum time as the stem on a fully grown MJ pant can get to an inch thick with no problems and the root ball can and will fill a 5 gal pot no probs..peace.
