Well she's never had any nutes but this week i'm gonna feed her for the first time because she has some light green leaves but besides that she looks pretty good right nowNo not lack of nutes, just stress in general. Some strains are more likely to throw 3 leaves but under optimal conditions will throw the normal 5's, 7's, etc.
Cause of this could be...
Non optimal lighting
Temperatures too high/low
Large swings in temperature
Improper light schedule
Light leaks
Etc
Just any stress caused to the plant of non optimal growing conditions
