Single Jack47

Greetings from week7 :) Everything is going well, at first the plant was a little behind but I was in no hurry There is never a break in my training , I stretch a little more after each watering . I wanted to reduce the fertilizer a little because the leaves are too dark green, but it seems like phosphorus deficiency starts on lower leaves , really in this period ? I dont want to use scrog strings but i think i can just lst 45th day 1.5 L nutrient water with carob extract and i use michoriza 49th day 2 L nutrient water with calmag and fresh aloajell
