i got 4 outdoor ladies..I live in the northeast and my average frost date is about october 1st which is 2 weeks away...Temps are scheduled to get down into the mid-low 40s this week..I dont want to lose everything due to frost...Also dont want to chop plants that arent ready and wont get me high...they are California Dream and Mazar and have 8-9 week flowering times..They look good and healthy but could use more weight..When would be a safe time to check them? how do i tell or figure it out? thanks!
