Ak-47 Auto [First Grow]

Getting bigger and bigger:) Sprayed it with some Vita Race by Plagron a couple of days ago. I also actively perform LST on it, nothing major really. the weather this week is supposed to be a bit colder, though I think it's better after the recent hot days. It’s starting to pack some bud while still stretching. The weather this month seems kinda rough, the temperatures go down to as little as 11*C(52F) which kind of worries me on a longer run. Day 45: It seems to have a magnesium deficiency so I haven't fed it anything but but water pH 6.5. After trying to flush it turned out to be unsuccesful I have bought a magnesium rich nutrient made exactly for the mentioned defficiency
