Is this nute burn from a previous feeding?

Is this nute burn? It hasn’t progressed much so I hope I’ve dealt with the issue but thought I’d still check,
7 1/2 weeks into flower
Growing indoor in coco, nutrifield nute line

What you have there appears to be a classic presentation of a potassium deficiency.

P98,
If Renfro is right...and he usually is...the other question then is why. Are you locking out K or not feeding enough. On your nute line...what are you feeding and how much?

I’m using a + b and bud burst, was using PK heavy but stopped using last week. I follow the nute calculator on the nutrifield website.
I am on week 8 of nutes, I know they’ve got another few weeks but was just going to taper down from week 9s amounts after I’ve finished the guide.
Ph is 5.7-6.2 and I don’t have an ec meter.

P98,
I'd do that taper sooner then later. Almost for certain...you're locking out K with too much of something else.

Flush the system with florakleen or any other product that removes excess salts. Then refill your rez with fresh nutes and bobs your uncle.

"General Hydroponics FloraKleen removes fertilizer residues that can accumulate over time in hydroponic systems, growing media, and potting soils. Use FloraKleen monthly to purge your hydroponic system or potted plants of excess salts that can accumulate as a result of regular fertilizer application. FloraKleen is an excellent final flush, and can be used at any time to dissolve mineral and salt buildup. Its high concentration and low price make FloraKleen the economical choice for maintaining your plants in both hydroponic and soil-based environments. "

I don’t have a res, I hand water, I use coco and I use nutrifields not general hydroponics

Pic,
Since you're so close to the end...I'd do a final flush of epsom salts. To help with flavor...
