CAN YOU START NUTRIENTS A FEW WEEKS AFTER YOU BEGIN FLOWERING???

I just started flower and Im using Flora Nova Bloom only at this time. Im planning to use GH GoBox week after next. Is this an unhealthy or unwise choice to start additional necessary nutes this latish? Thanks in advance.

Depends on how rich your soil is, how big you plan on growing, how many transplants youll be upping containersize to, lots of stuff. Id reccomend calmag after the first month and food used sparingly but a bit of added nitrogen never hurt a vegging plant.

Should be OK your plant needs different doses of food throughout flowering just like adding a pk boost around week 5 or 6, I would add it gradually about half or quarter of the dose it states and if it's OK after a few days with no burn or stress up the dose and go from there
