Honestly it cracks me up when he comes to me with questions! He lived in Cali for awhile just to learn to grow well but is clueless about certain little bits. I’m just getting ready to harvest my 2nd mini grow . When he had a room full of seeded plants he had no idea why . I get samples and side jobs from him so can’t complain
LOL Which “leaf” did he trim??? Looks more like a “comb” than a cut. Definitely did not hurt her at all. Healthy looking plant with decent light penetration, I would let it veg some more and start taking out the lower stems internally that will not produce. Maybe take a few fan leaves out but she looks good to me.
