Yeah but I would like to know so I can hopefully avoid in the future. The taco and the burnt margins. Tip burn ive had before but not the side edges

Heat stress. What is your temperature and humidity?

Looks like you’re taking really careful measures with your setup! The burnt edges and taco-ing might be due to a bit of light stress, even at 80%—Mars TS1000 can sometimes be quite intense that close to flowering plants. Maybe try lowering the intensity to 70% and see if it improves. Otherwise, your VPD and feeding routine sound solid! Keep up the good work, and let us know how it goes!
