is 20-20-20 all purpose good during flowering

i have been feeding my plant this Peters all purpose 20-20-20 fert. during veging and now 3 weeks into flowering....now is it ok to keep feeding it that..i know its better to have a higher p level ...but would it affect the volume of budding ....my plant was lst. and it has bout 8 potential sphere points but haven't increased in density ..all flowers are about a pinkie nail to a dime size still relatively small....i just want to make them bigger.....their under 4 cfls 27k in soil 3 weeks into flowering total growth since thanksgiving out of a bag seed of sum rare orange looking baby chronic midz ......

I use Jacks Classic Blossom Booster 10-30-20
you should flush and start your flowering nutes on next feed.
Hope this helps

the 20-20-20 is good to use up till the stretch. you could keep using it, but the 10-30-20 would be better.

All of the flowering nutes I have ever seen advertized have a very low Nitrogen count. I use 2-8-4 Fox Farm Organic Tiger Bloom. Everything has worked well so far. There are so many choices I just picked one that is organic. I think the reason for the lower Nitrogen is to let the plant grow thick not tall. I dont have any experiences with anything else.

ok thanks so i should flush it ????its been flowering for 3 weeks........so i should just buy some nutes... i have no funds now thats y im trying to get away with he 20 20 20 nutes
