Leafs yellow, burn spot . Deficiencies or excès..?

maybe nitrogen? what's your pH i'd ensure that's in a proper range befoer doing anythign i suggest... lookin over your nutes, i see you add pk... wihtout doing the math on PPMs this can be dangerous, as p and k lockout several other things when they are too high -- K is the more likely culprit based on typical feed concentrations and such.. but... could try slightly bumping N, but looks like more than 1 symptom showing up and the plant is fairly helthy otherwise, this is why i'd lean lockout. dial back a bit and see what happens. it doesn't require a "flush". you are in soil, you likely alternate or have some irrgation with water-only correct? maybe add 1 extra of those then when you fertilize again dial down your PPMs use an online calculator to figur out ppms from your labels.. i have a spreadsheet that might work for liquids, but might not.. it's linked in my gd profile comment section. if an online calculator doesn't mention specific gravity, it's output is poopy information - not usable, unless you mix dry nutes. if around 6.5pH and you find K is > 210ppm by more than an insignificant amount, that's almost certainly the problem.
