Anyone knows how to apply Plagron Bat Guano as top dressing for autoflowers and is it fine to do it in week 2 when they only 7-8-9 days old? Thanks

Plagron Bat Guano has NPK 3-15-4 so definitely use it during flower and WITHOUT bloom ferts or there is a chance overfeeding here's the trick it's low on K so u have to add some K fert... not very convenient (i'm using potassium sulfate/K2SO4)

At that age/size, you will most likely burn them to death. Guano is very high in phosphorous and is best used during the flowering phase when requirements are high. Top dressing now is unnecessary..........and could be dangerous too. Normally, if you started with quality soil to begin with, additional feeding should not be needed for roughly 4 weeks.

if ur soil is mixed with ammendant so ur plant is ready to go till more or less bulking week more week less , then u top dress her. if ur soil is free i think best way is to learn on internet, personally i'll use classic chimical nutrients with this soil but surely u will find smth talking about top dress ( and i think top dressing only with bat guano is not enough) good luck

depends on the soil you are using.. you may not need to add anything for weeks or even a month or 2 in some cases.
