When to add flower nutes?

My auto kush plant is 4 weeks old today on 420 and I can see the beginning of the flowering stage happening already. The soil I have feeds plants up to 3 months but should I add bloom nutes or just let the pre mixed nutes do their thing all the way through?

It depends what soil are you using, I it already has nuts mixed in then you can still use bloom nut you may want to really cut back on the recommended feeding amounts.
