So you are ready, looking at your most recent photo. You have lots of white hairs this is where the buds will form. Therefore you need to introduce your bloom nutes now, this is around the time I would do it but you don't want to cut out the grow yet (but you should have a manufacturer schedule, if not Google one up) as the plant will enter now what we call the flowering stretch where it will double in height at least. 🌱👍Happy growing get that pk involved!
