I hate to burst anyone's bubble or stir up "conspiracy" theories, but.
You might be shocked what is in the rain these days. Barium salts, Boron Salts, Aluminum Salts and who knows what else. Don't you see the jets flying over your head spraying that shit in the sky, and then the whole sky clouds up with weird unnaturally symmetric patterned clouds and then it rains...... or mists super fine aerosol shit.
The stuff they spray makes the atmosphere more conductive in certain areas allowing them, they "the bastards" to manipulate the weather among other things. Research it, you'll be surprised how deep the rabbit hole goes.
I have been suspecting that some of these chemicals are responcible for mutations and cellular damage in plants for some time now, but of course I don't have the money to build the lab to prove it.
Ive been wondering if that's causing my nutrient troubles as well...
