When should I introduce soild food to my Scaly - Breasted Lorikeet?

[Ashley Ireland]

I have a 3-4 maybe 5 week old Scaly breasted lorikeet and im currently spoon feeding it wet mix. It does eat it on its own sometimes and i do watch like i was told. Im just wondering when should I start introducing soild food or dry mix? Another other information you think i might need is greatly appreciated thank you.
Its not the one in the photo. I do have another bird : )
