Yep.
Once you get a few grows in you get a lot more comfortable. Especially if you already have some bud put away and aren't growing it because you need it. Nothing sucks more than being low and bud and then fucking up a plant.
I'll talk him over basic shit. LST, how to PH his water before feeding, that sort of stuff.
I got massive downvotes on reddit yesterday, some dude was starting his first grow and he had this insane feed schedule with A + B nutes plus like 5 or 6 other additional nutrients to be added in various amounts at various weeks. I tried to explain that he really needed to just grow with the A+B nutes and learn from there, not add a ton of variables and then when things go wrong not understand the problems. New growers just love to go all in on tons of stuff like bud enhancer, silicone, sugar, etc etc. Like you wouldn't even know that that silicone is completely fucking your pH up unless you've done a simple grow and seen what ph being off looks like.
