Is this nutients burn or whats happening?

That might be a nute burn...but it does not look bad. I burned my plant recently, and afterwards read in the MARIJUANA GROWERS BIBLE that I should be diluting 50%-66% rather than start full strength. I even burned my buds, but flushed the plants with plain distilled h2o for a week.
If your plants continue, flush the system. I use a DWC.

FloraGrow 3-1-7 (recomended, 5ml/10l at this stage)
FloraMicro 5-0-1 (recomended, 10ml/10l at this stage)
FloraBloom 0-5-4 (recomended, 15ml/10l at this stage)

I Also have to add that this feeding chart is for Hydro/Coco and Im using light-mix. I belive light mix has very low NPK. I will call the store later and ask about the NPK.

1/4 recommended strength....

When you have a prob like nute burn, still not saying that it is definitely nute burn, you have to flush right away and flush properly. If the soil is not flushed properly, it will take longer for the plant to recuperate. If your using RO or distilled, you definitely want some cal mag, like mededcannabis mentioned, and B-1.
