Special Queen #1

I’ve been using banana peel for my potassium and phosphate in the soil and cucumber peel for nitrogen. I’ve grown up in a family using these for normal plants such as veg and flowers and it works a charm and seems to be on these guys. I just want to know if I’m over watering them (water them 1 litre every night when the sun goes down because it’s 29 Celsius of a day time here)
