Trying to add humidity by misting the tent every morning but that seems to only last a few hours because of how well air is circulated.
Other than that, she's growing faster than the Kush and looking very healthy.
Update 7/22: she started to show a deficiency in the first set of leaves. Knowing this is fresh soil and has never been flushed, I immediately suspected a nute lockout due to PH. Flushed with ~850mL of PH 6.4 water and 8 hours later she had a mini growth spurt. Nice save!
