Phosphorus Def. And Small Yield!!

How do you know it is a phosphorus deficiency? Are you sure. Phosphor is the main building stone for buds. If you have a deficiency of it your buds would be small, but the plant may still look healthy. If you are sure go to any garden centre and look at the fertilizers (if there is no growshop in your town are country). On all fertilzers there is an NPK number. These are the three main ingredients for almost all plants. N= natrium, P=phosphor and K= potassium. Buy the one with the highest P and give to your plants. Hope you work it out, good luck.
