I think she's burnt?

I fed my 4 girlies yesterday and today my two early veg stage ladies have some severely burnt leaves, so my presumption is nutrient burn but having not seen it this extreme before I wanted to post and check that I'm guessing correctly. Is that what this is? Some other leaves were much worse than the one in the photo.

Thanks everyone.

What are you growing in? That much damage in 24 hours is pretty extreme.

Coco coir with perlite mixed in.
And I used the same nutrients that I have used for their whole grow but in fact more diluted.

It was really scary to see the damage. I should have taken a picture of the other leaves. I just hope it doesn't continue

I’m not a coco grower, but that explains why it happened so quickly. Are you measuring ec and ph? Did the coco get dry?

This is my first attempt at growing so I don't even know what EC is!
But I'll check the soil ph tomorrow.

I don't water the top of the coco coir, I check to see how deep it is before I feel wet substrate and then water below the surface. It helps prevent mould to keep the surface dry.

I found an Apera EC60 meter on eBay for $30, you should check that out. They have the PH20 for under $30 as well.

I have very recently had some experiences with digital meters. I am getting different readings between 3 of them. One combo meter is an apera pc60 with the calibration kit.
I gave up and use the GH ph drops I have had around forever. Kind of a pain, but I trust them.
This is after I kind of made fun of somebody for using drops....

Like I said, not a coco guy, but I know that EC (electroconductivity) or alternately PPM of dissolved solids (parts per million) is very important to know. Thats how you measure how much to feed, when your media needs flushing, etc.. PH of the nute water is also critical, if the the ph is too high or too low certain nutrients/micronutrients will be locked out. Also, never let coco get dry, it will become hydrophobic and lastly are you watering to runoff?
