What am i doing wrong? and how can i get success?

There's so much you could be doing wrong it's hard to tell. Growing Cannabis can be as simple as you want to make it. As long as you understand the basic needs for light, space, temperature, humidity, airflow and nutrients you should be able to grow some plants 👍🌱

Keep things simple and easy - if 1st grow - forget all the ph/ec/ppm just grow the plant and as your experience grows you can start to consider ph,ppm, ect

I'm not sure where your going wrong either my friend everything seems above board to me. I am myself having trouble with auto flowers and this is my first attempt at them and im really not liking it they are so sensitive to everything its pretty difficult to cultivate an auto properly I think personally I'm just sticking with photos and clones I will run autos outdoors though :) I would suggest trying to get her started in a rock wool cude first then when notice roots plant her then. It can't hurt :) might give her a little kick start with the rooting :)
