Vato,
Indeed, as Growin' Dad says...reading your plant is number 1. It might seem that reading the directions on the bottle would be good enough...by many peeps including myself have found that labels tend to be on the high side. The more you use...the more they can sell you! lol
So I'd keep it half strength for awhile longer and then ease up to 3/4. Always watch color and tips. Super dark green and tip necrosis mean back off.
