Auto Bombshell in Coco, third Auto

Saw some amber on the buds, so harvest will be soon!!! So accidentally I got another two discoveries - fast-flowering and low-smelling strains. My growbox is 40x40x100cm. 20cm - is light + 20cm growpot with coco, and 15 cm to get some space to the light. So for the plant is only apr. 45cm of height. So veg period can be fast, not like in the case of a big growpot and growbox. And there is really no sense in long flowering. So in my case, fast-flowering strain really is a thing. Another problem is noise, so an interesting variant for a future grow is to have low-smelling strain and simply totally quiet 1-2 computer 120mm fans for ventilation. But in case of smelling strain, there is a need for filter and apr. 35dB inline fan, which even at a lower speed is too loud to sleep with in the same room without some ear-protection. About feeding - fed 2 or 3 times with 500-600ppm, but the plant seemed hungry - lighter leaves, lower leaves had become yellow, Mg deficiency because of typical light spots, so I decided that plant got a nutrient lock. So, flushed and next time gave clean water, then 500ppm - clean water (<100ppm) - 800ppm and today will give clean water to get rid of Nitrogen. Because the harvest is soon!!! Btw, the last 2 weeks watering every 36 hours - 3 * 0.75L and have 200-500mL of leftovers, preferring 12-26-20 nutrients and CalMag.
