im new to growing but im growing northern lights#5 its a tough plant can bounce back from anything. ive budded to small plants one that i topped and one that i didnt i found for me that topping didnt really give me the result i was looking for it kind of just split the main cola into two smaller colas. im now doing lst which is really working nicely i have two in veg and one flowering. as far as nutes go i dont use them so i dont know i just use soil, cfls, tap water, and LOVE
