my widows are now in the 8 weeks of flowering,and i want a head stone more then a couch stone,so i should wait untill the trichs are cloudy,however some sites say that white widow develops the white christals in about 10 weeks,which i liked the look of,but this will give me a couch stone if im right,what happens if you let a plant flower for too long,does it lose it thc content as im scared im not going tio harvest at the right time and lose its potentcy,ive ordered a magnifing class but its not arrived yet,can someone clarify what ive said and give me some advice on what to do,hope this makes sense,thanks
