"Looks different to what a use. Mines is just a wee tub of crystals. But its still magnesium sulfate.
1 teaspoon per ltr usually sees me good. Dissolve it in a wee cup of hot water just to dissolve it quicker. Pour that into my 1ltr spray bottle of cold water. Give a good shake. Take plants out groom away from lights.
Give em a good misting. Underside of leaves too.
Raise your lights as high as they can go. Put plants back in. And lower lights once the leaves have absorbed it all or when they look dry.
