Tomatoes are also my first try and currently waiting for a Third round! I also planted Pimiento Habanero, passion fruit, lettuce, basil, coriander, and cannabis being the latter the most difficult one to care for, without a doubt. I have been feeding them home made plant food that I made based on coffee leftovers, ashes, potassium with banana peels and sugar, and some other ingredients that I learnt to use as nutrients. I am very happy with the experience and the result. Still ongoing tbh!
