what’s wrong with her

Black tips around the edges kind of spotty towards the center now. I am growing white widow auto flowers at first I thought it was a calcium def because I’m growing in coco with perlite and advanced nutrients ph perfect trio with bud candy piranha overdrive and big bud I also have flawless finish I haven’t used yet I gave it cal mag with the water ph’d to 6.2 the problem progressed so I flushed the plant the run off ph’d at 6.3 I then noticed some leaves were trying taco towards the center of the canopy I thought it may be light being to close I’ve moved it and nothing has changed what am I doing wrong

Sorry about the multiple post

You over did the Nitrogen some point and now they are slowly finishing
Not sure you can do anything but let them finish at this point
You must recall when you first noticed an issue?
Didd you maybe add a PK booster recently?

Yes I did 2 ml of the overdrive mid last week

But I first notice the two week ago after coming home from a 5 day trip

like herb said, nitro issue but that plant shouldnt be doing anything but being flushed at this point, happy harvesting soon. if you were still at early flower or veg you could deal with this but you will be messing around with potency at this point. flush cut and try again.

Thx
