Veg vs. Bud nutes?

I understand that the veg stage needs more nitrogen and the bud stage needs more phosphorus, but is it okay to use nutes with more nitrogen in it (4-3-3) in the budding stage? I'm kinda short on cash and just wanted an answer before I went out and spent more money.

By the way I'm using General Organics BioThrive Grow for my veg nutes.

And I was also wondering about the light spectrum. Is there a major difference between budding with white/blue lights and budding with red lights?

Oh and I also heard that organic nutrients eliminates the need to test the ph of the water, true or false?

I would suggest research a bit about dolomite lime. That will eliminate the need for Ph your water. Without dolomite lime you would need to keep an eye on the ph just to make sure you have the stability in your grow. Yes you would need the bloom nutes to flower regardless unless you have an 1-1-1 ratio of npk such as 10-10-10 you could bloom in that if you want. However, too much Nitrogen could cause a lousy taste to your smoke.

I'll definitely look up dolomite lime and other budding nutrients, thanks for the help man
