Okay, it’s pretty clear by now that it’s nitrogen toxicity, but nobody’s telling you how to fix the problem. I guess I have to step in and help another grower, probably Italian. I’d use enzymes and aim for generous runoff (the water that drains out when you water—around 15–20%) to gradually flush out some of the excess salts, while the enzymes help the plant process the excess nitrogen. Obviously, don’t give it any nutrients—just water at the correct pH with enzymes added 😉 Feel free to check out my grows if you like. You popped up while I was looking for myself in the rankings, and when I see someone who’s clearly Italian, I naturally want to see how they grow ☺️
