Critical Purple Auto: First Grow

Increased apical bud ppfd to 1450 at this time and decreased EC of custom made nutrient solution to 1 due to minor signs of nut burn that I suspect is due to a insufficient amount of CO2 to balance the high ppfd and nut inputs. No CO2 meter so better safe than sorry. I also trimmed back ~1" of topmost canopy buds I'm order to maintain a level canopy and promote further development of lower and mid bud density/mass. Sidenote: I know, breaking all the "rules" here but I'm trying to gather as much experience with my first grow as possible and test the limits of the cultivar despite perceived autoflower time constraints. So my focus is on architecture, cloning, breeding and revegging in the long game by exploiting the 10% rudialis hardiness. May be horribly disappointed in the end with lower yield if unsuccessful but that's just my style--experimentation. "Can't clone autos"--"Can't reveg autos"--"Don't fim or top autos"--ect. I intend to put those presumptions to the test and ultimately see how and how many genes can be activated in a single cultivar by changing abiotic and biotic conditions, hence the very erratic light schedules & wavelengths, feeding strengths, ect. P.s My major in college was cell and molecular biology if that shines light on my seemingly haphazard grow approach.
