Usage of Plagron Bat Guano

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.

sorry my bad ... i got confused top dress with foliage spray ... da, a stoned thing i guess

normally if your using amendments they are applied once every 3-4 weeks. sometimes 2 but not often. Mix it into the top layer of soil. add more soil if their is to many roots and the pot has some volume left. Follow the directions for topdressing on the bag, it should give a rate of application like 1tbsp per 1gal of medium or something maybe like 1tbsp for 8" pot or 500g per m2. If it does not have one. google and AI are your friends and can help estimate a rate.

don't understand why you want to spray bat shit on your plant ... ues it in the soil

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.
