I've only grown feminized seeds and one regular random seed that ended up being a female sativa and they all looked like that right before they show preflower.
cool, what can cause hermie.....i know stress can but my plants have been healthy their whole lifes so far
Stress and genetics. Are they bag seed? Some plants have a slight hermi tendency. Couple male flowers can go unnoticed and make seed without any real hermi problems.
