Dinafem Critical +2.0 Autoflower

Sorry for missing last week's update, have been renovating so grow had been put on the back burner. Have had some potass def showing as I've been feeding the remaining nutes I'd pre-mixed at around 350ppm (Had no water to mix up a new batch), run off has been coming out at 50ppm so not nute burn though it could be stressed a little by the lights being only 16" away. Have since switched to Maxibloom as I just drop one teaspoon in my 5L mixers and I feel it's a better ratio of NPK for flowering. Have re-added Calmag to bring base ppm of my soft water from 50ppm to 150/200ppm and for potass issues in coco. Have also started adding Shogun Sumo Boost since last week, just a slightly cheaper alternative to Canna Boost. Bud sites starting to more visibly form now, smell is fruity but weak and leaves getting quite sticky, sticky residue left on hands when brushing through. Would have expected this to finish around mid April but because I've been underfeeding past week might see it finish by the end of April now unless it suddenly takes off within the next 10 days. Most main branches have all stiffened up now so removed most of the LST ties. Have been defoliating some of the leaves but not gone too mad as not had the time.
