In coco, water with nutrients every day! The pH of the solution should be 5.6-5.7 pH. It's time to start feeding with nutrients! Begin with 50% of the dose recommended by the manufacturers of your nutrients for the vegetative period. As the plant grows and develops, slightly increase the nutrient dose, but don't exceed the recommendations! 👆
Try to water with enough liquid so that 2-3 centimeters of the coco surface dries out within 24 hours. If you have a 20-liter pot and you've just transplanted, start watering with 400-500 ml around the plant so that the roots grow wide in search of moisture. After a week, you can water with 1 liter; it will be ready for that! 👌
It's recommended to water the plant in adulthood with no more than 10% of the substrate volume! That is, in your case, a maximum of 2 liters! But it can get too hot, and it may drink a lot, so you might need 2.2 liters after the middle of flowering, towards the end of the harvest. 👆
Good luck, buddy! ✊😇
