hey there , keeping it simple is the best solution for sure , but diamond nectar is a great thing and you always need cal mag, floralicious is good too but it changes the taste slightly , not in a bad way but it's a thing ... The main idea is to properly understand the timing and the function of the additional nutrients so that you dont harm the plant : it's much more important to reduce stress in flower than to feed a lot of nutrients. Hope this helps ! 🚀
