I am close to the first portion of a three or four stage harvest. I will be snipping the majority of the colas in 5-9 days. After that I will go back on nutes for another 2-5 weeks before another flush to snip the middies. After that I will repeat the process possibly two more times. As this is the case I believe I will be fine on time as long as I can get some pollen in the next couple of weeks (shouldn't be a problem considering the sacs are beginning to open). Also as the flowers age the trichomes will get more cloudy and amber meaning each part of the harvest should produce more of a couchlock stone than the one before it.
OK, now I understand I forgot your doing a gradual harvest! Thanks for being so patient with me! Sometimes my own density amazes me! Too much of this stuff going on with me >
