Help pls, carencia? Exceso? I don t know

Over fed and burned. In soil a schedule of plain water/plain water/feed/plain water/plain water/feed works well.

I use these nutes and never had anything like this. Have you over loaded on the amount given at 1 point or more recent than that or test the pH of what your feeding because the information you have give should be working, so this is my guess to lockout... Hope this helps. Happy farming.

Medium appears very dry and looks like potassium deficiency on some leaves with a bit of calcium deficiency on other

I see a few symptoms, leaf taco happens when the plant transpires too much, so it curls to reduce it's surface area and protect itself. Commonly happens from too much light, and/or too high VPD. Older growth effected first from yellowing and tip burn, immobile nutrient deficiency or ph out of whack possibly, dark green looks dark, possible nitrogen toxicity, so much going on with this one, without a proper diary one can only guess at root cause. Normally when there is multiple things all over the place its PH.
