What’s up DGC. So I know using Epsom salt is common but what about dead sea salt. Sea salt is loaded with macro and micro nutrients I was thinking about using a tbl per gallon for last few weeks before flush. Any hp on this topic would be much appreciated!

Dead Sea Salt is still 30% sodium chloride and I wouldn’t use it.
Sodium chloride can’t be good for plants in any amount. This is why fleeing armies salted the earth, so plants wouldn’t grow
Ok I’m a bit confused What about Epsom salt and to give more insight into my idea. I read an article about a place in Italy that was famous for there Roma tomatoes and I guess they flooded the crops before harvest with natural sea water and this was supposed to be there secrecy to have such flavorful tomatoes. Thought I could simulate this with seasalt.
Epsom salt is magnesium sulfate. Magnesium and sulfate are both essential elements. Almost pure sodium chloride is known as table salt. The oceans have about 85% sodium chloride. The Dead Sea Salt has far less sodium chloride but still has far too much. Apart and in small amounts is good. Sodium is not essential but is beneficial and can be used at up to 60 ppm. Sodium can act like a replacement for potassium. They can both open and close stomata. Chloride is actually an essential element needed but only in small amounts. Less than 5 ppm.
100% agree with mystro, but I will add there are some interesting ways to utilize sea water as a source of minerals for plants.
Korean Natural farming methods include a few recipes for using diluted or fermented sea water as a garden input. You’d want to be careful messing with this sort of stuff, but I’ve heard good things from people who use these recipes
