I would start at 1/4 strength and if after a couple feeds bump it up if it shows no negative effects..............

Ok thanks for the advice mate also would you use a root stim? Im worried about over doing things

I use Rapid Start from General Hydroponics for that, works quit well, LIke auto said if you are new to that particular strain you want to go light on the nutes until you can determine if she is a heavy feeding strain. Do you have a PPM meter? If so a good rule of thumb is to keep your PPMs under 250 for the first 2 weeks, then increase gradually over time
