flowering nutes..?

I have a questioln about flowering nutes... im usin mg potting soil... I used it durin vegging and these past 2 watering I've been flushin it out... and I know I shouldn't add flowering nutes until 2 or 3 weeks of flowering... so I was wondering since im usin mg soil n theres a high risk of nute burn.. especially since I got burnt durin veg if I should even use flowering nutes?? jus hesitant...

yeah you need to use nutes for the flower stage. If you've flushed your medium as you say start with a 1/4 strength nute solution and work up slowly. I usually never feed more than 1/2 strength recommended lowest dose. Try another mediu next time. Something thats not pre-nuted.
