i wrapped my brain on this one for awhile

im almost positive i know what is

the thing is this growth was exibited from the 3rd set of leaves after the cotoly whatevers long before nutes where introduced, i thought it may have been the soil and i flushed it and ket it dry weight method, new growyh the same flushed again leaves started turning pale and needed n so i put toghether a nute mix that all of the other plants love and within a day the dark green came back followed by vigorous growth but still deformed

the other plants of the same strain have this too but it is sporadic
