Hey bro! I haven't been visiting the threads like I should the last week or so, so I missed this when you originally asked (not that it was directed specifically at me).
To me, this is an easy question to get a wrong answer to. The first thing to consider is the type of soil mix you are using. If you're using
OF, you won't need veg ferts with auto's... in fact, you probably don't need to add much in the way of ferts at any time, even though almost all of us who use it, do add bloom ferts.
If you're using pro-mix or another unferted soil-mix, you probably need the veg nutes.
