Nute Burn?

When this plant was young she went through a nute deficiency that started with browning from the middle of the leaf. This looks different. It is starting from the tips and is now along the edge of the leaf.


Now it is moving into the inner leaf

Every leaf has burnt tips. I recently raised the nutes to 1500ppm. When she was at 1400ppm is when i started to notice it. Now it is getting worse. She is starting week 7 of bloom today. She is a 8-9 week flower plant. My friend who has been growing for some time told me to bloom her for 11-12 weeks. Is this nute burn? Should i reduce the nute concentration?

How do i correct this?

Looks like nute burn to me, better back off the nutes for a while or the leaves will continue to burn from the tip in.

Flush with enzyme, and molasses, and b52 for a day. Ph'd. she'll recover a lot quicker.

okay thanks
