Hello all,
I am new to the community. I recently purchased this 12 year old Tiger Bark ficus Bonsai (pictured below) after wanting to get into Bonsai for years.

I have shears for clipping, a water meter to gauge soil moisture, fertilizers, wire, everything I could possibly need (I think!)
A couple of novice questions though, roughly what # on the water moisture scale should my Bonsai be at (0-10) ? I have seen 3 floating around online but nothing for my specific species.
I live in Miami where it is very hot & humid, but the tree stays inside all day.
Also, the yellow leaf below... what does that indicate? Ignore the scar, but I have had a few leaves like this so far. Turn yellow with green splotches.

Thank you in advance for the feedback... once I get the hang of everything, hopefully I can help out too!
