Ma plante présentes des tâches sur les feuilles ...

High Hix57, All your plants got a small nutrient burn from receiving too much nutrients. And the deficiency is from receiving the wrong type of nutrients for this phase of the grow. Next to that you are giving the wrong pH value!!! Coco should be lower, you give pH 6.2 this is for soil, you should give around pH 5.7 for coco!!! (Very important!!!). My advice is to stop giving the grow nutrients, up the blooming nutrients to 5 ml/L, bring down the seeweed to 3 ml/L and up the Cal-Mag to 3 ml/L and bring down the pH to pH 5.7 Make sure to always give till at least 50% runoff on coco to prevent nutriet salts building up inside the coco. This will raise the EC and the pH as well. If you follow these changes your plants will be thankful. Happy Growing Buddy! 💚
