How much granular fertilizer should I give my north lights auto? I have a "general purpose" fertilizer (grains) which has an NPK of 6-3-3 and potassium grains with 2-0-20. I find it difficult to dose as it releases its nutrients over a period of 3 months... Gave 25g of 633 in w 3

@MadeInGermany, hey man! Thanks for the reply on my question! But it doesn't completely answer it. They advise 75g/10L pot in general for plants in pots and 100g/m² for "average nutrient needy" vegetables like carrots, spinach,... But the thing is: these are doses that are meant to last for 3 months and you're supposed to feed them at once. What I'm thinkng is: I gave her 25g at day 18 along with a good watering. Now I'm waiting for the pot to become dry again (probably around D25 or so) and with next watering I'll feed her some additional fertilizer. Only thing is I don't know how much to optimally give. Maybe another 25g to be safe? Or should I add another 50g to get to the recommended amount for a 10L pot (which I guess is still alright since she's in a 15L pot)? Or should I feed even more and just flush her when I switch to flowering nutrients?
