Started the week by feeding with last week schedule.
The smell started to become a problem which forced me to prioritize my exhaust filter problem. Managed to clean the pre-filter and fix the high static pressure areas and the exhaust air filter is now working nicely.
The next day, I topped above the 7th node as light was starting to be too strong. I still have some room to raise the light but not much.
Over the next few days, I will be stretching the new stems horizontally by pushing it for now and adding a net later. I will also need to defoliate the lower levels that don't get any light.
Edit: After consideration, the yellow tips I was getting near the top was probably due to underfeeding and not light burn.
