Nute burn or Deficiency?? +rep for help!!!!

Hi RIU,
I have a 2 1/2 week old plant that is either showing signs of nute burn or some kind of defeciency hoping you can help a fellow grower out. Thank you and I will rep all answer.
You can see in these pictures taken yesterday that the leaves look a little burnt or defecient. Two bottoms leafs are getting bad were you can basically break the bottom leafs, they seem to crumble. Now the plants get all yellow. I just switched to advanced nutrients. My ppms were at 600 but now I put it down to aroung 400. Room temp is at around 79-84. Ph-5.5-5.9. Any help would be great thank you.

Bump. please help

im not a hydro grower,but looks like a deficiency

Thanks "mygirls" for your input.+rep

If you get nute burn will the plant basically stop its growth including the roots?? Beacuase I check my plant today and the plant is still growing and the roots are growing nicely. I dont know I need help I dont know if I should up the nutes or back off the nutes.

almost looks like ph is ur meter calibrated?ide put a fresh nutrient solution in the res and check the ph every couple of hours,to make sure its stable.

Yes, I made sure my ph meter was calibrated yesterday. When I checked m meter it was only off .1 which isnt really to much. It seems like my plant started to show yellowing after I changed them to advanced nutrients. Since its like almost 3 weeks in I didn't know were to start from on the advanced nutrients. Seems like the botaniacre pro bled was way easier to use than advanved nutrients but I'll adjust.

Thank you.From what that chart says its a deficiency. So if its nute burn does the whole leaf turn yellow or just the tip?? Cuz its my whole plant thats some what doing it. But isn't 600 ppm for a 3 week old plant a lot for advanced nutrients????

That second pic is no good. If the color of your first pic is showing on my monitor correct, it just looks like N deficiency.

Hey maybe it is an N defeciency I thought that the ppms were kind of high but maybe Im wrong cuz Advanced Nutrient says I should be at 800 ppms. Thank you mindphuck +rep. Anyone else.

nitrogen underdose or overdose.
are u using any veg boosters?
lay off em for a few days and watch her go lush..

Thanks + rep. No im not using any veg boosters just the Advanced Nutrients Grow,Bloom, and Micro.

Post nutrient solution label. You should use something like N-P-K = 30-10-10 for vegetative stage. Are you using air-pump with air-stone? I would suggest! For 2 1/2 week old plant 500ppm should be max in my opinion...

If your pH is OK then its too much nutrients or salts are dense in root medium. Flush with pH 5.5 water and make new nutrient solution with 400ppm from nutrient with 30-20-20 proportions (with microelements)
