Is there a problem?

Berry Haze Plant 2 weeks before harvest, great health, but this cola does show many leas turning yellow or dry up, is here a problem ? its a dense cola ...

You are way farther away than 2 weeks from harvest. More like a month. Looks like nute burn is your issue. Back off the nutes a little.

Yes agreed... you are much farther out then 2

looks like a month more lil bit of a def it looks like.
