it's in fox farm soil nd has been recieving only water for the past week or so.

I was feeding them general hydroponics but seems they were getting slightly nutrient burn so I flushed her real good and been feeding water for about a week almost 2 I'm guessing maybe it's time to feed her? I'm not to sure

How long has it been in that soil? In my experience my plants normally start getting fed after a month living in new soil. I also use a ppm meter and never go over 800 ppm when I water. If you don't have a meter then it's best to start under what the bottle recommends and move up. Also, unless I'm mistaken, gen hydroponics is for exactly that, hydroponics, so it should be pretty complete. It should be sufficient to give your plant all it needs so it's definitely better to start low and move up slowly when feeding
