So i am just over 4 weeks into the grow of an ak47xtrm auto...the main stem is as bid around as the average thumb..I have here in a bubble spa in a 2x2x4 grow tent...i have raised the lights as she has been near it for almost 2 weeks. I started tying the limbs down..well to my surprise i noticed 3 days ago the main stem split in two!!!..i thought the plant would die but it shows no effect..the leaves if anything or greener none are dying or wilting..is this normal.or has the proverbial shoe not dropped yet??
