deficiency? or nute burn?

It's hard for me to identify the issue I am having with my plant. The bagseed plant is about 3 ft 7 in tall and is in day 40 of flowering under 150w of cfl. It is contained in a 1 gallon aerogarden reservoir with pH'ed distilled water and the recommended amount of DutchMaster One, it is a one part nutrient.. prior to using dutchmaster i was using the stock AG flowering nutrients that came with the flower package, I have switched to the dutchmaster and bought a pH kit and pHed all my water to around 5.9-6.0. It has been a few days. Can anyone tell me what may be causing these issues? temps are steady around 78F/50% humidity daytime and 73F/60% at night. Roots are healthy and res temps are around 75F. I have an additional air pump for extra oxygen. I just cleaned the reservoir and added fresh pHed and nuted water with a little less nutrients than recommended. Could anyone tell me if these new nutrients will fix the prior issues. since before i had no clue on the pH nor had any instructions on nutrient levels.

here are some pictures.

I also forgot to mention that the plant had these issues before using dutchmaster and before pHing my water.. I guess I should wait to see improvements with the new nutrients. but can anyone diagnose this?

...if your pH was out of wack, you could've been locking out. ...I've seen similar looking plant issues caused by cal./mag. def....hope they bounce back for ya. Goood luck.

I checked the pH of the remaining water from before and it was around 7.0, It could have been up and down as well, who knows what the aerogarden nutrients consist of.. it could have been the entirely wrong mixture.
