Lot of bud growth in the 4th week of flower, some of the pistils have started turning orange. Feeding is still the same, watering as needed/whenever the pot gets light. Some leaves have dried out and yellowed at the very very tips, but it doesn't seem very serious. Probably just too close to the light. I raised it by a few cm. I don't have a jewler's loupe, so the macro lens on my phone is the best I can do in terms of checking the trichomes. This is not ideal, but I think I can safely start flushing in a few days. Flower should be about 5-6 weeks so I think if I start this weekend i can flush out most of the nutrients out of the buds by the time harvest comes around, hopefully before 5th of July as I'll be travelling, so I'm hoping to cut and start drying before then, and leave the plant in the hands of my roommate until i get back. So far it seems like it will be done way before that though, so hopefully I might even be able to trim it myself.
