I was supposed to take pictures and top the plants to make clones this week. Life intervened and I barely managed to water them. They wilted pretty bad and all but one came back nicely, that one is struggling. One grew right into the lights after getting watered and got burned pretty bad. It's a mess in there.
I wouldn't be sure whether a plant was male or female until putting it in flowering light cycle for a few weeks. I recently grew DJ shorts Blueberry F5 and Blue V2, which I was able to re-veg, but the two big Blueberry F5s have not come back and I am about to call them and replant, but they did produce hundreds, maybe thousands of seeds crossed with the male Blueberry F5 I grew out and then shook all over them. It's amazing how little flower you get when the plant makes seeds. But now I have enough seeds from my initial pack to grow out 50 at a time and pheno hunt for the most blueberry I can find. Gonna put them in solo cups and re-veg them after a handful of weeks in flower, and transplant to 5/7 gal pots with a fresh JMS (JADAM Microorganism Solution) to help ease the transplant and boost root growth.
Your bonsai trees look cool. I'd wanna be sure before I chop any. You could stick it in a little cardboard box with a light hanging above it on a 11on/13 off timer and you should know for sure a few weeks later
