Hello and welcome from Kent UK
1. That enclosure is far too dry. The substrate needs to be damp - all of it, not just the surface - to raise humidity
2. It is impossible to raise the humidity to the level needed by a young tort in an open table. Youngsters also need to be kept at a minimum 27c/80f day and night. To do this they need to be raised in a closed chamber. A plastic tent type cloche from Amazon could be used to cover your table. You will also need a ceramic heat emitter (CHE) and thermostat to achieve this.
3. That substrate has white bits in it. Torts need to eat calcium, but encouraging them to eat the substrate is a very bad idea. I cannot understand why leading pet suppliers do this! Buy plain coco coir or fine grade orchid bark from a garden centre, DIY store or even Amazon
4. Those reptile bowls are not suitable for tortoises. They are a tipping hazard. Use a terracotta plant saucer for water; sink it into the substrate so your tort can walk in easily and surround it with pebbles to stop the substrate being dragged in. Use a piece of flat rock or slate, or even the rough side of a wall tile for food; this will help to keep your tort's beak in shape by abrading it while he eats.
5. A baby like this isn't ready to spend much time outside yet. Maybe a couple of years.
6. Those dial thermometers are at best inaccurate. Get a temperature gun type thermometer like this
