AN Heavy Harvest VS Sunleaves Guano

I'm starting my outdoor grow I'm going to be growing purpleberry and maybe bluedream I'm using 7 gallon pots and one I think is 10-15g with sunshine mix #4 I'm not going to be able to cost the grow very often maybe 3-4 weeks apart there is water supply I have water lines hooked up to a timer so that's not going to be a problem the only thing is the nutes I currently have AN Heavy Harvest spring blend and was wondering if any of u know how good this stuff is I'm debating on using heavy harvest or going fully organic and using sunleaves guano will the guanos last for 3-4 wks if I use it as a top dressing or will the plants not get enough nutes the heavy harvest says that it can go up to 5 weeks before I need to add more I don't want the plants to starv if I can't visit them for a 3 or more weeks

i have the heavy harvest stuff....it works well...its hard for me to dose properly thought.. i just throw a couple handfuls and scatter it evenly. I only use this on BAGSEED, for good genetics i would use tea or guano, even if its every 3 weeks

Im thinking I'm not Gna use heavy harvest what guano should I use never really used any of this stuff what would I use to make a tea

im also kinda curious about this tea stuff. hahaha

some guy said not to use guanos in teas in reference to microbial teas i guess
can you meke fertilizer tea also? like concentrated fertilizer or something
