very slowly growing plant

gorilla glue auto, came up from soil 14 days ago. picture shows how much it grew the last 3 days. dont think it will "explode" anymore? my other gg auto plant with same watering schedule, light, etc is doing great meanwhile

Some of the best plants ever grown were slow growing and even runts
Damage can also be a factor either in germination or transplanting
Patience is my only thought
Well that and is that dry coco ?
Good luck

it is medium soil. too bad it is not photoperiod seed so I cannot hold it in veg, so it really should speed up soon!
