Compost tea is a great feed, along with worm casting tea (after making tea add the compost/castings to your plant) liquid seaweed, banana tea in flower,...these are quick feeds and will do with a completely organic soil. You are feeding the microbes in your soil when you grow organic. For long term feeds I use blood meal, bone meal, and I'm gonna get a lot of flack for this one....powdered milk.

I've also used Earth Dust grow and boost and I've used Gaia green...but these must be timed right.

Oh, and I have used Cal Mag with organics if the plants need it. Some people say it kills microbes, but I haven't had to use it often enough to worry about it the few weaker microbes it might kill.

Roots organics terp tea dry amendment line. Tablespoon per gal of soil top dressed at the beginning of flower and then the bloom boost at the half way point and you will get results like this!! I do a few more things but it’s really simple man don’t go crazy with it and buy every single down to earth dry amendment there is and end up overwhelmed. The terp tea has a blend of all the different amendments in the proper ratio so all you gotta do is top dress it and water in.

I've heard bat guano makes your buds taste funny is this valid??
