THE 30% RULE:

Never modify a plant in any way that causes more than 30% of the plant to be either healing from cuttings or severe training, at one time. Move the plant in stages and take only cuttings that allow two thirds of the plant to remain UNTOUCHED until the third you modified is healthy and growing normal again.

Thats how you prevent hermies or total sex change.
