I can't find a inexpensive humidifier. I see misters or foggers like this one below. Is this the sort of device you use?: https://www.amazon.com/Coospider-Terrariums-Humidifier-Paludarium-Amphibians/dp/B07VVNP7F3/ref=pd\_bxgy\_sccl\_2/130-6037743-2984160?pd\_rd\_w=PfaTb&content-id=amzn1.sym.7757a8b5-874e-4a67-9d85-54ed32f01737&pf\_rd\_p=7757a8b5-874e-4a67-9d8...
You won't need to add nutes until you start seeing the first pistils popping up around day 30ish. Even then just use 1/4 of the recommended strength. I also highly recommend getting a cheap moisture probe off of Amazon. Plunge the probes balls deep in the soil and do not water until you get dry reading from at least 3 different spots. This will prevent overwatering and all of the soil pH issues that come with it.
I would buy this LED if you have a 2x2 to a 3x3 space. Would work great and cost less then 100 bucks.

Yeah usually I wait at least until the plant is 12 inches or so tall and then bend the main stalk down. Then throughout the life of it you can form your canopy. I train all the way until it starts budding, and even through flower sometimes. Use these clips also or something similar: Engineered Essentials USA Made The Original 90 Degree Plant Trainer- for Low Stress Training (LST) and Plant Training https://www.amazon.com/dp/B08KSMM9HS/ref=cm_sw_r_apan_glt_i_7BP18MF6Y0A0RWFYDEP4?_encoding=UTF8&psc=1
They will change the whole training experience for you. Basically if you can't fit the stem around those clips its too early to train!
Sorry for the long message but figured I could help.
