Ezzjaybrush is speaking facts, in fact some brands will recommend you flush the medium every 2 weeks using their products because the feeding ratio to advertise are just way to strong and if you wash all the problems they originally cause it mean you will use their products more wastefully and then buy more.
There is one user on here that goes by the name NobodysBuds, and they have a great understanding of N use in flower and veg. and If I can recall correctly the amount of N does not change all that much from flower to veg when they calculate it all.
Cannabis feeding/fertilization are also marketed towards people who maybe confused about some of the options and this is why there are 10+ bottle feeding programs vs legit shit you mix into the medium. Making you think you need a lot more when you don't, then theirs the issue they are selling a diluted version to yourself vs the pure cut.
Use an TDS pen and monitor your EC to avoid any potential buildup and lockout from excess feeding is the best advice I can give yea ATM.
don't need to use their feeding ratios and the plants will love it.
Best Of Luck and Happy Growing!
