It's been an exciting week. She's in flower and has started to stretch. I'm not sure how big of a stretch to expect but I've trained the branches out wide and flat to manage height. The new growth also seems to be coming in with very skinny leaves but then looks normal after a day or so.
I am still only watering with water ph'd to 6.5-6.7. I have not added any nutrients since the seed was potted into the amended Coco. I will top dress around day 50 and again durring mid flower.
