Not picking on ya XV. I've killed more seedlings, clones and plants than anybody, but every time i killed something, i tried to learn about WHY. Over time, i finally got it sorta figured out, and although cannabis is a weed and can grow almost anywhere, there are some fairly narrow parameters needed for getting the best out of them.
I remember dumping in ferts and feeding the plants, only to have them dead and fried by next day. NOW i realize it was because the ferts were way too strong for them.
A friend in Iowa has tap water thats over 1000ppm because he lives in a heavy agriculture area. I've lived in a place where the ppm was over 500 out of the tap, and that wont work either. Any tapwater over about 200ppm will cause probs with the plants.
Some soils already have ferts mixed in when you buy them. Its good to use a ppm meter to check the "runoff" of water from the pots, especially if adding stuff. That goes for ph too.
Del mentioned his PH. The target numbers should be about 5.5 to 7.0. There are a whole host of nutrient "lockout" issues than can be caused by the PH being too high or low. If you know the "starting point" of your PH & PPM, and then know what those numbers should be, its a lot easier to succeed.
Check out this chart. It shows the ph where each mineral is most available to the plants.
