Plant does look good and I like the little setup you have there, classic little stealth grow
I am hoping you just dumped some excess perlite on top of the medium and your entire pot isnt filled like that or you will be watering a couple times a day. For future reference I wouldnt use anymore than about 35% perlite to your medium, gives plenty of drainage and space for root growth but doesnt over do it causing you to water more often.
