Nutrient Burn

[quietlybinary]

Hi Everybody,
Is this directly related to nutrient burn? Do I have to balance the PH after mixing nutrients too?
I am having a go at non-organic nutrients for the first time. I used about half a dose of nutrients and this came up.
I am used to using Bio Bizz and some other nutes and this is the first time I am trying a house brand of a local hydro shop. From the photos I know like it has been a while since it happened. I am only feeding once a week as the plants are in supplemented soil. I fed all three of my plants the same thing except for this one with the respective nutrients. This occurred on the two largest fan leaves.
Thanks in advance for your help!

That's not nute burn https://www.growweedeasy.com/nutrient-burn-cannabis That looks like you dripped something on the leaves?

It almost looks like you splashed some nutes on there. Is that a possibility?

Thank you SirSmksAlot and alltatup you are right I did splash my leaves with vinegar mixture to try to get rid of spider mites. I did this to all my plants and it messed them all up to some extent but none of them had these same markings in their leaves. I think maybe the solution I used just sat on these leaves different because of their shape. Thanks so much for your insight!

2 things... check the PH before spraying leaves and never spray during lights on. Best time to spray is right after the lights first shut off if possible.
