hey all, begginer question

so how is every1 doing? :)
i wanted to know
when shud i start fertilize my plants?
i got 1 plant that sprouted (came out of the soil) at the date 6.5 (5th of june)
and another one that sprouted at 8th of june
is it the time to start?
i have the bio nova fertilizer

and how much fertilizer i should mix with every 1.5 liters of distilled waters?

wait a couple weeks. you want the babies to get healthy by themselves first.

Three to four weeks of just water however I'd suggest a few drops of Superthrive, it will help speed up your root development but just a few drops per gallon of water.

yea thats why i asked, every guide i read says start fertilize after a month
