Hi everyone..
Im growing 2 autoflowers from fastbuds, lemon ak & Blue dream. Around 3 days from seed.
I am using automated watering, so i won’t be able to feed the plants nutes automaticly. Therefore i wanted to use top dress feeding instead of my biobizz collection.
i am using biobizz light mix soil, which should run out of nutes in a couple weeks.

I have never tried topdress feeding before.
Can i top dress feed with worm humus only?
How much, and when to do?

I cant get my hands on Gaia green in my country.
