Small plant

it's a runt but probably not genetics, probably there was a lack of cal mag and especially a lack of chelation agents meaning the roots didnt get prunned enough so the root system stayed small, small roots small plants. In nature a plant's roots are always getting naturally prunned then regenerating, and this regeneration pushes out new growth also above ground. if it wasnt in flower i would recommend root prunning which is where you litterally clip approx 10% of the roots off with a pair of sizors, crazy but it works surprisingly well. Hope this helps ! 🚀
