First grow

Your going to want to start flushing soon fam! To give a good flush u atleast need like 10 days of time. You dont want your ladys over ripening in that period of time. The real question is how ripe are u looking to chop at? And will your plants be there in 10 days. Right now a few of those pics the pistils are standing straight out and the whole cola is still very white with hairs. And in the others the plant looks further along. Browning pistils ,they are curling in and receding. All signs of ripening. I'd have to say ur plants are not going to finish at the same time. Start flushing the plants I described as ripening and keep up with the nutes for a bit longer on the real hairy white ones! Happy growing and stay lit fam!
