You do understand with ZERO parameters it will be hard to help you in any way right??
This would happen to me if I'm running organics in 5gal pots and water until runoff. You wash away all the nutrients. Suggesting calmag is a meme but honestly, give it a lil calmag lol. The old leaves won't improve much but the new growth should look better.
Listen man, I kinda moved on from Reddit to get away from the egomaniacs. I simply stated that if he's using organics (typical for new growers) and he's watering until run off (typical advice) he will run into issues is micronutrients.Calmag is a meme because no one knows what it means. 30 years ago Cannabis growers knew what it meant. It meant you bought shit fertilizer from a pesticide company that grows tomatos, or from a dirty "organic" scrap source. The bandaid? Calcium iron magnesium to antagonize the Mn. The Mn tolerant line of soy is called Calima.
