Bat guano..Is it safe for seeding? if so how much do I mix?
and when I replant how much do I add in my mix with blood,bone,kelp,and worm?

What's the NPK of your bat guano? Seedlings will do just fine without any nutes and if you're going to be transplanting later anyway you might want to wait and mix the bat guano in then. Fish emulsion would be a better first fert (after the cotyledons dry up), and personally I only use bat guano (the high P kind) in tea during flowering if I think they need more P than what's in the soil amendments.

Well.. how do you know if they need more??
and i dont know the npk yet..just like a basic mixture..how much?
as for the tea how much do you mix in that?

The weed Gods tell me when my plants need more P.

If they just don't seem to be budding as heavily as they should and I can't find anything else wrong, they get bat guano tea. The guano I use is 3-10-1 and I brew the tea at one tablespoon per gallon of water. One tablespoon per gallon of soil or water is the general rule with most organics.
