Hi
@SpaghettiGuy the secret of defoliation is to do it slowly with an interval of days, and little by little for the plant not to stress and to delay in growth. due to the size of your plant I think you should wait 1-2 weeks before defoliating again. I think you should change the light period to 18/6, plants need a rest during the dark period is when they develop most in all aspects. good luck mate 👍
