most plants can take a bit of nano once they leaf up a bit. Depends on the crop, broccoli, cabbage, lettuce and so on, once you get three or six leaves i usually hit them, then I use plant timings so this changes of course.
My broc I have is a purple strain that runs 75 days approx. i usually hit it on week 4 from germ.
Most stuff runs on three or 6 leaves, then i use markers eg x days before pre flower, one week after set, then every 3-4 until I cut mid bloom, before harvest.
I feed my pot the same way bro, I dont use week guides personally, I use growth markers. EG I feed one month before bloom, 7 days before bloom, then again one week after bloom, then I feed to mid bloom as the plant physically changes, i use this as my guide and not the week guides we all offer.
I will be doing a master class on this on the BOX blog :)
