to tell the difference VERY SIMPLE, take a clone and find out that way or, put to 12 /12 after atleast a foot tall prolly bigger... After , sometimes less then weak lil white hairs will appear at the top only at first , about the first 2-3 stocks down. now i hope im right but what i hear is...
im a medical grower in wa and just started my first crop.. THeres absolutely no way unless clone not even then that ur gonna have white hairs yet.. i had 3 plants i grew for a couple months, one was 2 feet and bushy, the others were same age and way smaller.. on the big plant took me less then...
