>>657673I'm just using cheap (€1/litre bottle) regular all-round liquid fertiliser for all my room plants so far (pic related, I hope you can read the element symbols) once to twice a week or so (depending on how fast things are growing) because I'm kinda reluctant to pay top dollar for "special X plant fertilisers", will that do?
I know Cucurbitaceae (pumpkin family) are in general drawing lots of nutrients, so once I'm planting them out into the garden I will previously mix in fermented compost from the pile, and then plan to add fermented stinging nettle extract (high nitrogen) when watering them weekly or so
Pepper? Can you really tell when it hasn't formed real leaves yet? Because we hadn't had any in the garden for many years, so no idea how seeds could have ended up there
