Phosphorus (P) is necessary for photosynthesis and works as a catalyst for energy transfer within the plant. Phosphorus helps build strong roots and is vital for flower and seed production. Highest levels of phosphorus are used during germination, seedling growth and flowering. Deficiencies will show in older leaves first. Leaves turn deep green on a uniformly smaller, stunted plant. Leaves show brown or purple spots.
Plants need N-P-K as well as minerals and micronutrients throughout their life.
Pot in vegatative growth need P, yes, but the demand/need for N is much greater.
The #'s you listed had very little N.
Pot needs very little N after the first 3 weeks of flowering.
fruit bats have P poo, insect bats have N poo, i like bat poo. the stuff is strong , you could mix up both, the plant will take what it needs when it wants, but only if it can. Bat poos do burn plants so cation my friend. i lasyt used King Guano, phillipino fruit bat shit. i followed the insrtuctions and all seemed well. until a deer or rabbit ate my plants. I cursed the gods..
