ok so ive heard that during vegetation weed needs alot of N and ive heard that 5-3-3 npk would be the best but what would happen if i used a nute that had 29-2-3 would that just kill the plant or help it grow better lol i know this might be a stupid queston but im new at growing and i already have this nute in my house and it would help if i didnt have to go buy one thnks for the help
I'm almost positive the middle number (phosphorus) must be higher then the other two for vegetation, but I'll let someone else confirm.
Explanation of NPK and fertilizers Chemical fertilizers and organic fertilizers show their nutrient content with three bold numbers on the package. These numbers represent three different compounds: Nitrogen, Phosphorous, and Potash (Potassium), which we can also describe with the letters N-P-K. The three numbers listed on fertilizer labels correspond to the percentage of these materials found in the fertilizer. What does each nutrient do? In addition to other properties, Nitrogen helps plant foliage to grow strong. Phosphorous helps roots and flowers grow and develop. Potassium (Potash) is important for overall plant health. Be aware that high nitrogen fertilizers will make for quick growth but weaker plants that are more susceptible to attacks by diseases and pests. Fast, showy growth is not necessarily the best thing for your plants. http://forum.grasscity.com/absolute-beginners/73015-grandpas-grow-guide.html
