Plant is budding but Leaves are yellowing and tips are yellowing

[Dawghouse]

My plant is in its last month and it is budding but the tips of the leaves are turning brown and over time turn yellow and brown. I have a pic below of what the leave looks like when it starts turning. as well some of the upper leaves are curling upward. Any advice would be great thanks.[attachment=o286112]

Got any more pics? The yellowing fan leaf could be nute deficiency, but with curling tops I'm thinking cal/mag...
Some pics of the whole plant would be a help

The leaves are curling up because they are praying for nutes, feed them!

Magnesium deficiency imo. Get some Cal/Mag solution from your grow shop.
Have you tried just giving her a flush/rest/feed?

what are you feeding it? What is the ph of the medium and the water.

Could be ca/mg but I doubt it. Looks like the ph is out of range. Also its time to boost the P-K.

Check the schedule for the nutes you are using.
