I have Some Blueberry Cheese and Some big Bud plants at the moment, iam also using Canna range but growing in Coca substrate.
Iam in week 7 of Veg and tomorow iam turning to 12/12, i was just wondering should i use my veg nutes for the 1st week to boost nitrogen, or start using canna boost straight away? or even mix?

ur help will be much appreciated
