I'm not seeing a deficiency in those. Color's even, no margin burn or spotting, and the new growth coming in looks fine, so there's nothing there you actually need to chase.
If anything she's a little hungry rather than lacking something specific. Day 44 in veg at 28-30 she's transpiring hard, and 2 ml/L of Terra Vega is a light dose for that stage, so I'd nudge the Vega up a bit and read the next set of leaves before treating it as a deficiency.
