My soil was not prepared, it only had 3% organic matter, and it had a lot of clay.. and I watered very little. I think the nitrogen acted too much. I did leaf analysis of the leaves, but everything seemed perfect. I think the colour may be due to excessive maturation due to high temperature, but I'm not sure. But this watermelon began to create cracks on August 15, Dap 48. It's traditional melon, and I get fat very well and quickly. The plant was about 350 square feet, and two other watermelons of 70-90 rounds appeared when I removed the plant. I mean, 3 watermelons were growing at the same time
