Do you ph your water?

A pic of the entire plant would give more clues as to what happened to it.

have you been using reverse osmosis water, or maybe distilled water?

 

[chuckie86]

I been using tap water but sits of usually before I use it n I don't pH the water

 

[GrowinDad]

I think you answered your question. Get a PH on what is going in and your soil. If six weeks into flower, I would keep the humidity lower also.

How low should I keep the humidity

 

[wiethe20]

Low humidty tricks the plant into thinking that it needs to protect its water aka producing gland heads.....40% or lower

You need to ph your water! My tap comes out at about 7.5-7.9 with high ppm's. it would most definitely help a whole lot if you ph, plants take up nutrients better with the ph range of 5.5-6.5 me personally im 5.8-6.2

It is obvious from the downward clawed leaf tips that you are over-feeding. Combine that with temps on the high side of acceptable and your leaves will get crunchy.
