What's causing these dry, crispy, orange/yellow/brown leaves

Anyone know what's going on here? I thought it was windburn from the fan but have since moved fan in other direction and it is appearing on other leaves now. I doubt it's nute burn cause no increase in food except I started PK 13 14. It is only on one plant out of 4. Thanks

Hey growmie, that ain’t windburn. That’s nute burn, crispy tips, brown edges, it’s textbook. Especially since you said it started after you added PK 13/14 it's pretty clear she didn’t like the boost. One plant reacting like that means she’s just more sensitive. Could be uneven runoff, salt buildup in that spot, or just a picky pheno. Happens. You’re in late flower, so it’s a good time to ease off the feed anyway. Either give a couple low-feed waterings or flush lightly if you think the buildup’s bad. She’ll still finish ok. Just don’t push her or she’ll crisp up worse and the buds might suffer for it. Good luck bro 🤞🍀♥️✌️

burning of some sort. You not letting wet leaves stand in the light are yea? a good feed system does not need a PK boost. its just wasted product.

Week 9 you were showing high high ec soil was cooking at capacity and tips were showing clear osmotic stress or at least what I'd expect from a 1.8ms/m Hard to tell from pics but looks like too much nitrogen but I'm not sure if it's lighting. Applying foliar sprays in 6th week of flower is not recommended. No idea what your humidity is but if it's over 55% it's a definite no no. Hard to tell, you have been using same dosage of A and B from start to finish. If your medium was full and at it's salt capacity. You upped feeding for 2 weeks after. Capacity of soil should fall somewhere between 0.3mS/m to 1.8mS/m. Id Guess it's up somewhere in the 2.4 ms/m or thereabouts right now.
