Too much water and you'll drown the roots and the plant will slowly drown and will suffer and could wilt. But too little water and there wont be enough to replace what its losing and it will wilt.
Not little nutrients and your plant will yellow due to lack of nutrients. But too much nutrients could lead to excess salt buildup ultimately leading to nutrient lockout...which is also yellow due to lack of nutrients.
So on and so forth...
So its not necessarily that its conflicting information, but it just that its more nuanced and complicated than you want it to be. Its not always as simple as "this is causing that". Its often "this is causing that which is then causing this, etc"...a multitude of factors all layered and intermingling. As others have posted, there are charts which will help you pinpoint the end point problems. But no chart is going to tell you the reason. You need to figure that out yourself since you know your situation better than anyone else possibly can. Any conflicting information you do get is because people dont 100% know your situation and so are throwing out possibilities which although they seem disperate, could both potentially factor into the eventual correct equation. If you want to grow weed, or any plant for that matter, properly and productively then you'll need to put a bit of effort into learning stuff and not just relying on charts or other shortcuts that dont exist.
