Bat Guano or Fish Bone Meal for Flowering?

Both need the microherd to break them down to be plant available. I'd prefer the FBM since it has proportionately less N in flower. Easy to top dress with. Good luck. -granger

Lambs quarter is full of P and around where I live 45 N, it's blooming right now. I picked a half 5 gallon bucket of chopped up lambs quarter, then topped it off with assorted wild flowers that are also in bloom like sweet clover, and whatever else, flower wise, I could find to fill the bucket, then I added about 1/4 cup molasses, filled to the brim with water. Then I put it in a warm shaded area to rot a week or two.

And that will be my flower fertlizer. 5 gallons cost me a little molasses and an hour of wandering around in a field of flowers. I might also use kelp meal in teas. I bought a 50lb bag at a local feed store. That cost me the equivalent of a 1/4 oz for two or three years of kelp meal. And both of these have everything a flowering cannabis plant needs. Well compost and that, lol.

For outdoor this year i used a product called "Dr. Earth #8 Flower Girl". 4-10-7 worked amazing as a late veg / flowering amendment top fed at 1 cup per 20 gallons. Plants greened back up and are loving it. I'm pretty sure it contains fish and bone meal, and could be used for an amended soil.

A lot of people are moving from bone meal to fish for some reason though.

I also find that high P guano is to loaded with N to be used in midflower, i use it as a starter after cuttings have rooted..

@Scrappy first i thought that you where talking about lamb meat LOL, then i goggel it and found that is a weed that i have all around me, thanks for adding yet another source for home brews...

This is a great resource for homemade fertilizer, if anyone wants to explore this topic more.

Some indonesian (.5 - 13 - .2) works really well for me around week five. I usually use about a tablespoon mixed up and watered in.

If i was to use FBM i would topdress a couple weeks earlier to allow it to begin to decompose in time for it to be available.

funny you say that - ive noticed that too - even though it says its a zero in N , there's some N in it for sure sometimes - thats why i won't use guanos anymore after week 2

More p or k for flowering?

You need more of both. Plants still use a lot of N til about the 2nd week or so in bloom depending upon the strain, but the need for a lil more K begins right before blooming when plants have been or are being vegged a lil longer and all thru the bloom phase. More P is needed during the cloning, seedling, and bloom stages. If growing TLO try not to overdo it with the P, too much can affect the microherd in a negative way.

I guess the real question is why wait until flowering to add the nutrients the plant needs... How come its not already in your soil?

I think sometime those of us new to (or still learning about) organic soil "Just want to make sure" we have enough nutrients for the plants to finish properly.

I'm a big fan of Jamaican bat guano (0-10-0) and Foxfarm Big Bloom (.1-.7-.3) for flowering.
