Hello farmer of the future-get your magnifying glass out-look atthe little droplets (thc). when the start turning amber it over pull it.on some plants this takes a long time.when they turn amber,starts at the top of the plant,the cannibinal level shots up and potentcy starts degrading.as long as they are clear or white the are still producing.on some types of plants,like white kc you will be waiting a while.This is where patients is needed for the plant can just sit there and look like nothings happening for weeks.but something is and it will make a big difference in the wieght and potentce. havnt you had some smoke that may of had a great high but 20 minutes later its like you never smoked some. reason pulled to early. good luck-be patient.later
