Nute burn or Nitrogen deficiency? Can she have both?

The strain is green crack. I’m growing in coco and using cal-mag and general hydroponics flora series for nutrients. The plant is a bit over a month old. Room temp stays at about 70-75F.
She looks droopy in the pictures cause the light just came back on but normally she is perky. I think I might have slight nute burn but then it also seems I now have a nitrogen deficiency cause the bottom leaves are yellow and brown spotted, curling up, and kinda crunchy but its way to early for that to be normal like at the end of flowering.

@Xaz welcome to the forum. Depending on the pH of your soil you will be locked out of certain minerals which will show as a deficiency as these minerals are now immobile and can’t be used. Do you know your soil pH at all. Also those pictures are of no use as all you can see is purple, picture in natural light is needed to help us identify problems
@Cannabian I just love that poster :joy::joy:

It was a post card I got for my birthday a couple years ago, I thought it was a keeper!
