For those that don't want one more tab open, this is a response from CAASA:

By "DIY" they mean liquids mixed and packaged in-house by the shop owner or someone selling out of their home (unless they meet all if the licensing requirements, which is unlikely.) There is nothing in the law that stops people from DIYing for their own personal use. The law only applies to liquid being sold or given away.
So, it's good news bad news, in essence. At least there won't be issues with private DIY in ones own home for personal use.
