That looks like early pH lockout, not a true deficiency. John Innes composts can run a bit hot and acidic for young autos. Flush lightly with pH 6.2–6.5 water and let the plant settle before feeding anything extra. She’s still small enough to recover fast if you balance it now.

Hey! Looks like a calcium and magnesium deficiency… pretty common, especially in autos with sativa dominance. Hard to say more without knowing your soil mix. Also, definitely check your pH - without that info, it’s impossible to rule out pH lockout. That’s usually the first thing to dial in.
