Personally I would not. Before 12/12 I would check the ph from runoff if soil and flush. A day after flush and 12/12 I would start adding my bloom nutes per manf. instructions.
yeah I got that part but they aren't going to stop growing suddenly they will double or triple in height to build the flower stalk. That takes a lot of nitrogen that is in veging nutes. You can do what you want though, won't kill them to use flowering nutes.
yah sound like solid advise to me
i wish i coyuld affrd tiger bloom
but im using a micronutrient for vegging and a powder for my flower
i think im gonna switch the powder for a better liquid
your plan is good just add some all purpose plant food at 50% strength too theyll exsplode. i use Miricle grow 5$ a box works good with my canna lineup.
