Auto Pineapple Glue Advanced seeds

Hi there folks! This is technically the first ever MJ seed I germinated. Seeing the first ever set of serrated leaves was amazing I must say ahah. My noob ass made a bunch of mistakes which I think explains the very slow growth. I'm 3 days into the third week and I was expecting a little more size by now. Not enough light after germination caused the stem to shoot up for the sky, then I made the mistake of exposing the young seedling to direct sunlight outside which pretty much killed it. I was miraculously able to give it new life by repotting in another plastic solo cup, burying the extra stem in more soil+coco mix. I was a little clumsy doing the repotting so roots may have been exposed to light and thus stressed. Then hot hot temperatures prevailed where I live, and I made the mistake of leaving the cup on a sunny windowsill, on the overwhelmingly warm third floor of my house, thus heat stressing it some more. D'oh! Then I realized the water I was using was too cold for watering. (18 degrees celsius). I might have left the seedling in the initial plastic solo cup too long as well. 8 days is pushing it for an auto I've read. No sign of rootbounding when I repotted into the final 18l pot tho. I'm using a fair bit of coco which I've read can cause a calcium defiency. Last but not least, temperatures can be a little cold for a seedling at night here. My baby sleeps in a self contained outdoor shed but its door wont close fully so maybe it is still too cold for him... Oh well. This has been fun and I am very interested to see how it will end up! I apologize for the lack of pics early on. I thought to myself I'd do this for a later grow... Obviously changed my mind lol. THank you for reading! PS : Im sorry for the misleading strain name, I cant find nor add as a custom strain Auto Pineapple Glue. :/
