Should I feed my girl if she looks healthy?

I was just wondering if you guys and gals generally feed your plants even if they look healthy and are preforming very well, or only if they start to show signs of a deficiency?

my WW seems very healthy and is over a week into flowering at 20 inches and always seems to be nice and green and healthy and grows quite a bit, noticeably every day.

should i be feeding her regardless, or only if there's early signs of a deficiency? i don't want to OVER feed and so far shes doing great so im just wondering...

thanks!

i would feed her.. just start with 1/4 strength nutrients and slowly work your way up from there. a slow start is better than going nuts and burning the poor little girl.
