I don't use much guano so I can't really help you here. But this'll serve as good bump.

Hello guys, I've been growing for couple of years now and I fell in love with the coco as a medium. Everything was more than fine, until recently, when I've decided to go 100% organic from now on. I had 4 plants in 6.5lit containers of pure coco being fed with canna coco nutes, I did a massive flush and then added around 300-400g of red california worm humus and around 35g of bat guano as a top layer on the coco. After the first watering there was some slight burn, but then I've removed the top layer I had previously added and replaced it with rcw humus + only 5gr of bat guano. The Plants are doing fine now. However I can't find any solid information about how can I mix those two organic fertilizers I have, with the coco and at what ratio? Some people say bat guano shouldn't be mixed with the coco due to the high values of K, other say its fine in the right ratio.. I'm looking for help from some1 with experience in this. I am transplanting the ladies into 11lit containers tonight and for the moment I plan not to give any more nutes via the medium, but feed teas instead (if needed). Soon they will be going into flowering. Thx in advance!

I use jacks Pro 3 2 1, 3 days out of the week, I use Moab 2 days out the week, the other two days I brew a tea 1 cup worm castings 1 Cup bat guano 1 cup kelp meal , and all three packs from the beneficial bacteria s use this recipe brother your plants with thank you

Not sure how well organic will work with coco, but you can definitely try it. I would use teas, either leach teas or aerated teas, or a combination of the two. Fill your Rez with water, add however much guano you want, some kelp, maybe a carb and bubble it for a day or so. You can also do the same without the air stone and make a leach tea.

My fear with coco, is that it may not culture enough of the micro herd to make efficient use of the organic food. I love coco, but if I was gonna go organic I would use ffof or happy frog or some other soil.

Thx for the replies guys!
@Big Costa420 thanx man, can u please tell me how do u exactly brew ur tea and at what proportions? Atm the tea im feeding is from a recipe from the guano label => 100gr bat guano in 1liter warm water being shaked over couple of days and then 10-50ml per liter. I guess moab is some sort of nute, never heard of it, maybe I will google it a bit later :p.
@theother hey man i have no rezervor :D. I'm having my plants in 11liter containers of pure coco and I feed them the old school way.
This is a spontaneous experiment, I didn't plan at first to do this run fully organic and I still have my coco nutes enzimes and bloombastic :D, however there was a reason, that made me go organic, so I was like YOLO (i know u gonna hate me for saying this :D) .
For the moment, the ladies are in their first week of flowering in 11 lit containers, as I said above, you can still see the signs of the burn on some of the leaves, but for the moment they do not look sad at all :D
If the case is as @theother says i might consider buying some bio micro elements (i guess there are bio micro elements?)
However I'm open for advices and recipes on brewing teas :).
As of now the only camera I've got is my phones and I'd rather not take pictures of the "naked girls" with it :), however, if the situation gets critical I will find some, or if not i will take some pics before the scissors play :p

Edit: Having a look at the links in Seamainden's signiture, now im 99% the girls are suffering from phosphorus abundance early stage :D
