Deficiência

I think it's probably a sulphur deficiency - but no matter if that's right or it's zinc or any other micronutrient, your problem is that your PH is way out of whack. Micronutrients are absorbed when the PH is in a good range for them... since you're growing in soil, that range is BEST between 5.8 and 6.2... What you need to do is a good flush first because you've created a lockout situation... so you need to run 3x the water as is your pot size (if you're growing in a 3 gallon, then run 9 gallons of water through the pot). Make sure it's PH'd water... Then wait until the pot is dry before continuing on with your watering/feeding regime - and make sure whether you're watering or feeding that the PH is between 5.8 and 6.0. If you don't have a PH pen, invest in one NOW... it will save a lot of heartaches and avoid problems in the future. I happen to use and like the Apera brand as it's a bit cheaper but just as good as Blue Lab... and it's the one item I wish I had bought LONG before I did... I started out using the stupid little strips I'd dunk in the water/feed and try to match the color on a printed chart... should have just gone to a crystal ball reader, would have been just as accurate (i.e... wasn't even CLOSE to being accurate). Good luck!

Why I say PH is cause Zinc is affected different in different subs. So if I know your PH I'll be able to give a more definitive answer.

What substrate are you growing in? And what's your PH? It looks like a mix of zinc and PH swings.
