Zkittlez Autoflower

Hoping to start this week! Need to clean up my grow tent. This will be my third time growing, never succeeded into the flowering stage. First time I tried growing 4 plants, and it was way too much. Second time, I tried 3 plants, and once again I was overwhelmed, but I did learn how to trim the plant, unfortunately I trimmed it too late, but live and learn. I am still very much a sketchy novice, and about to attempt my third grow with 1 plant ONLY. This is also my first ILGM Zkittlez Autoflower grow, so I'm optimistic that this will be less stressful. Using 5 gal cloth 'smart' pot. I could use advice on plant training techniques, general autoflower growing, and coco coir growing. Expected Reasons for Past Failures: 1st Grow: Suffocated roots by leaving them without any airflow underneath. Also, poor understanding of how to manage the pH of the soil. 2nd Grow: I got lazy, not wanting to buy another fan or find a way to produce more CO2. So I left my tent open, allowing lots of light leakage. Thus, my plant grew wonderfully in the vegetative stage, but never bloomed or progressed into the flowering stage.
