I’ve not visited the forum for a long while so forgive me if I’m going over old ground.

I have bought my first bottle of Venom CBD 200mg Cannabidiol. How many drops do I add to my 5ml Nautilus Aspire tank? I,ve tried 5x drops and then gone up to 10x drops with no effect, so how much do I need to add?

I suppose there are tables and stuff to work it out but I’m hopeless using them generally. Thanks in advance.
