Possibly, but the pictures look very leafy. Doesn’t seem to be the issue. Unless this photo was taken after the foliage starting filling back in.
3 finger leaves are definitely a sign of stress. You see them mostly on young seedling growth and on a re-vegged plant if all other environmental conditions are optimal.
Then again, it could just be the strain. Look up the strain and see if others are seeing 3 finger leaves on their plants. If they were photoperiod plants, I would be majorly concerned about seeing that.
