Anyone know what’s going on here?

It's a deficiency but you have a very hot feed. That means one of two things. The first possibility is that your pH meter is off a bit and you're really somewhere around 5.5, causing a deficiency because the plant can't take up the right nutes. Calibrate and try again. The second possibility is your nutes are wrong. You may be using blooming nutes during veg. Your nutrients have 3 numbers on them (N-P-K). During veg, your baby wants a lot of N. Blooming nutes have almost no N usually, because in flower the plant doesnt need much. Hope this helps!

Low on Calcium or block. If run pH in 5s should add a bit of Cal supplement.
