Hello and welcome to GD!
Im growing the exact same strain and already at day 63.
A couple of notes, usb fan upwards dont actually do anything since hot air moves upwards ,your actually sending hot air back to the lights. Leave that out for now and in a few months you may use them to lower temps on buds.
Also those pH meters actually suck hard, i broke 3 of them before buying a PH pen. They are not accurate, they broke after a few days/week of use and will give you many headeachs .
Also drop that PH to 6.5. Thats the soil sweet spot for nutrient intake.
Good luck and happy grow 😉
