Hi bud
Your plant seems ok to me, the drooping could either be underwater or overwater as both have similar look but you'll know which it is by lifting the pot.
I'll.defo echo previous advice and carry out some LST to increase yield and get light to the darker places.
You said you've read and watched videos and lot contradict, that's going to be the same on here, or any other site as each of us find a way that suits ourselves and adapt to that style of growing.
What you will find though is we all want each other to reap our fruits and will always share great advice on pests or definiciencies
Me personally I would put her in a bigger pot, lift the light a little bit to stretch her up then lower it so I kinda get a 1.5" internode gap which then allows me to bend her over better and then lower the light back down.
I used to focus on wattage but since learning g more about photosynthesis I focus more on ppfd and find I get a better yield using lower wattage than I do frying my plants at the full power available.
Word of advice though is do NOT mix indica plants with sativa plants until you have more experience lol
Enjoy your growing and remember the 3 main rules...
1 no smell
2 no sell
3 no tell
It dont matter which order but theyre vital to a successful harvest unless you live in a place its all legal but then again you'll always find someone jealous so vest never tell lol
