Been watching newbies like you kill plants for YEARS! No game plan, just stick it in the dirt.

Haven't killed any plant in years, whether that was flowers, peppers, tomatoes, whatever, the nearest you would get to a plant dying when not expected was when my oldest cat developed a taste for a small olive bush we had and stripped the bugger bare. I use methods that have been tried and tested by myself and others for decades, and no plant of mine has ever died off unexpectedly, not even when I was stuck in hospital for 9 days.
Now, that's the easy bit. Getting a good yield is not so easy, and that's the bit where I admit I'm still learning which is why I say I'm getting a basic system working and then I worry about the "fine tuning" to increase things more. Have I made mistakes? Yes, but you don't learn shit if you don't make mistakes and if I can help someone NOT make the fuckups I did then I would say it's better to admit these faults and pass on what little experience I have so the more experienced can pass on the more "technical" stuff when necessary.
And if you think I have no "game plan" then you don't know how much time I spent looking at the likes of growweedeasy and Ilovegrowingmarijuana, how long I spent looking at what was said on assorted forums, and so on.
So wind your neck in, because you know shit about me or what I know or how quickly I can learn things.
