Ya I’m ruthless with moms too. Mine get full strength veg nutes (megacrop) and keep kicking along just fine. I also hack them back indiscriminately and they don’t mine at all. They’re under 4 compact fluorescent spiral bulbs which they just love.
Since I’ve switched to coco I have some in tiny pots that are like 3" cubed and I can’t believe how happy they’ve been the whole time. I have to hack them every week or so they just keep growing.
