Is She stunted??

What did you do since the last question? It looks like it grew from week 3 to week 4 in your diary. If you have made some changes, i'd see them through. Vigorous growth will not resume overnight. It will more likely be a slow march back up to full speed. if those nodes at top stay bunched up together as it continues to add new nodes, it's too much light as the cause. Must observe to know for certain. This will be overtly obvious if true. Autoflower's ruderalis genetics come from Northern hemisphere with short days for most of the year, hence they evolved to not react to long nights to cause bloom phase to start. They are not as robust to the heat and light intensity as a strain that comes from the tropics. Interbreeding and such makes this more difficult to associate any traits based on region of origin. In the end, it could also just be a runt. While it can happen to any strain, it happens more often with autoflowers. The leaves look healthy enough with some minor stress signs likely related to heat. I think i said it before.. get something that cuts the lgiht down... or shade the plant for a few hours per day and see what happens over 5-7 days. A mosquito gaurd type material might be perfect for all day long that still lets in majority of light.
