Yellow pattern on leafs... What is wrong with my Banana Blaze?

Hello, you have some immobile nutrient defeciencys. Possibly defecient in zinc, manganese, magnesium, calcium and iron. These are all important for plant growth but in much smaller amounts than NPK. strange to see defeciencys in all. Do you use tap water or ro? Maybe your tap water is very chlorineated or low in ppm... Do you check your ph of soil and water, it's out on the correct range? Could be a weak soil? Could be a lockout, do you water every 2 or 3 feeds? Hope you get it sorted.

Hello Calcium and magnesium. Calcium with the rusty spots. Magnesium with the stripping between the veins of the leaves. But since you're adding it in....id say the ph is off. Run 1 gallon of plain ph'd water and then come through with another that has a half dose of nutrients also phd. They say calcium is best around 6.2 but 6.5 for mag, so maybe ph at 6.5? Also possibly recalibrate your ph method it may be saying an inaccurate number. Good luck with the problem solving. ✌️

well if it didn't immediately get worse, it's more likey an abundance than a deficiency.. check your labels.. if you add plenty of Ca and Mg it can't be Ca or Mg def. checked pH? i'd bet p or k tox? both can cause a Ca or Mg deficiency (As can pH problems - likely to acidic if this is why) in the end you know your more recent behaviour better than i... i'd give another day or two of irrigation only. if the original problem stalls, but the plant looks worse otherwise, i'd considre rebalancing what you put into medium.
