Burn or deficiency?

Using success nutrients and their swazze technique. After my second swazze at the 3rd week into flower my plants will slowly and randomly start turning yellow. Originally thought it was nute burn but have used nothing but sugar water last 3 waterings and it’s only gotten worse. Starting to think it’s a deficiency as I’ll get yellow spots forming lower on the leaf without having burnt tips? Th

Potassium m8. IMO

Your girls look high in N for starters. What are you growing in and what are you pH-ing your feed to? And if the sugar water isn't doing anything but making things worse, I'd move on from that theory. Your plants look short on Mg...maybe there isn't enough in your feed, maybe your pH is off, based on what you're growing in or maybe too much N has it locked out. The devil is in the details. Good luck.

That’s become my guess... I don’t see traditional burn on them and cutting out nutes hasn’t solved issue. I’ll check the nutes to see where my K is coming from

Growing in a mix of promix, ffof and coast of Maine. I’ve been using this mix for years and the ladies were in this mix from their transplant in veg so I’m not sure it’s the soil. The problems start showing up after I whack off all the fan leaves at week 3 so I’m thinking I need to boost some nutes that are missing from the fan leaves not being accessible. Can we agree that it’s not nutrient burn? Appreciate the responses!!
