quick fertilizing question

Hi,

I have some bubblelicious, white berry and thai x super skunk that I am just about to put into flower. I have not gave them nutes at all, just soil and water. I got some fox farm big bloom and am going to start them on it. I have used foxfarm in the past, but always used the vegatitive nutes then switched into the flowering nutes.

So my question is since they have had no fertilizer should i start them at quarter or half strength and build up, or should i follow the instructions on the bottle and actually give them the normal amount. The bottle actually says to give them a large amount of it to start, but i am not going to do that.

thanks in advance

thanks for the reply, anyone else??
