when it looks like the shit you buy from your dealer! then its done. every one asks when there plants are done, and all the pistles are still white. if it doesnt look like chronic yet, then its not! happy growing!
also when you do think its done, becouse its does look like chronic, probly give it a week or two. i know its a bitch and takes forever, but may as well make it the best you can. and dont skimp on the cure!!!
