I use a 3 part GH nutrients, I just use a little extra of the "grow" kind during flower, that has a higher N content. Not too much though. And I only do it when I see leaves turning yellow.

how much is a little...and are you referring to adding more nutes with nitro in it?..because i have fox farm nutes

If you're only 2 weeks in, then yes, it's a little early for that too happen. Plants burn up alot of nitrogen during the initial stretching period(first 3 weeks of 12/12, or a bit longer), so it sounds like you need to use your veg fert(high N) a bit longer, before switching to your bloom fert/s. You can mix them too. If i were you, and it was feeding time, I'd give them half boom fert, and half grow fert, if you were planning on feeding full strength. If you were only going with 1/2 strength, I'd give them veg fert, then switch back to bloom, next feeding. Also, keep in mind that the leaves won't get green again, so don't overdo the veg fert, thinking it's not working. Basically, you'll just be stopping the yellowing from progressing, and even that takes a few days to take effect, so be patient. Give it 5-7 days, before you make judgement, as to whether it was enough, or not, then decide if they need one more dose. It shouldn't take more than that.

Also, if you get carried away and give them too much nitrogen, it can delay harvest time, and even make them look like they're reverting back to veg. Be warned, early yellowing, is a much better scenario, than that, because even with some early yellowing, you should still end up with some excellent smoke, and a nice yield.(as long as it doesn't get too outta control)

can i foilar feed with grow big that contains
6-4-4 NPK ...or will it need more nitrogen then that?

Don't water again, But tell us what you mean by "pur water" .... RO? softened? well? Big city tap? etc.
On leaf color, are there brown edges? (possible lockout) Any spots? (possible bugs) If possible a pic would help

You could have a cal lockout and adding nutes won't help. Give us a little more info on what you're doing & using.
& jawbrodt is correct in feeding during the transition

And yes you shouldn't see any yellowing at 2 weeks into flower.
