Nutrient burn? White Widow Feminized

[AndyBoi]

I believe my white widow plants have minor “nute burn”. I gave them an increased ratio of nutrients last night (24 hour prior to photos/videos below) only 1 of 4 is showing these signs. This plant is the most aggressive in the tent and has maintained the most ideal PH in comparison to the others. (Last night run off at 6.21 PH)

Is this nutrient burn?

Is it in need of a flush?

Much thanks and much Love

No new growth seems to be affected.

No new growth seems to be affected.

Looks to be a possible cal/mag issue.

Looks like nutrient deficiencies and the edges curling a little might be light or humidity related.

What a lovely little chart! Thank you both for your inputs. I believe it might be related to calcium or magnesium. I currently provide 1ml of CALiMAGic per litre of water with my nutrients. I add nutrients every other watering. (3-5 days. when top 1 or 2 inches are dry)
Does these seem correct?

For soil I ain’t the one to ask I do hydro sorry their could be other factors like what type of soil and etc that I ain’t got much of any clue about.

Calcium spots. Look to too much nutes overall. Too wet or cold or both rootzone. Or ph drifting. Many times its just too much calcium.
