Hi, my plant has nitrogen deficiency. Some ideas, how to add nitrogen to soil. Some natural solution would be great. But i will be glad for any idea. I fertilized plants on sunday, so i will buy some fertilizer, that contains more nitrogen something like NPK 1,5 - 0,8 – 1,3. Because fertilizer that i have now is 5% N + 10% P+ 5% K. And my plants are in veg stage.
