ive topped them today tho i know its a pretty noob move
id say each one has lost up to four lower leaves i guess that kinda yellowing and dropping should be normal and didnt mean i shouldve added more nutes right?
Topping ain't no noob move friend! In all honesty more complex techniques like scrogging and mainlining are bigger noob moves. Anyone that actually monitors efficiency, or works on a large scale will tell you, topping is the way to go. That or straight sea of green, but if you're trying to maintain low plant numbers for legal reasons, sog isn't the best way to go lol.
And no i don't think you should add more nutes. I would contribute your lower leaves yellowing to underwatering more than overnuting. Or lack of light penetration(but prolly not that). Lower leaves die sometimes tho, especially as plants grow taller. As long as overall and at the tops and middle are healthy, you are solid.
