Should I feed it the epsom salt just once, or do I have to feed it later on in the plants life...

And I think more problems are starting to accur here lads, I'll upload some photos in a bit when I get home

Im confused. Why is Gypsum even brought up. Gypsum is Calcium Sulfate. This is a Magnesium problem. Epsom Salt is the solution.

Keep in mind Epsom Salt has very little Magnesium per volume. I had to dump almost 2 boxes of it to get above the 30-40 ppm of it.

Oh and the original epson salt came from right up the block from you in Epson. England. Most now is mined as is no more or less organic than gypson which is derived the same way the original epson was.

Not sure what "boxes" means but 1/8-1/4 tsp per gallon works for me. I start adding it along with my Jack's Citrus a couple weeks before flip and stop a couple weeks before harvest. I no longer wait for the problem to show up.

I read up on how much to feed it on another site, they said a table spoon to a gallon, I use a 2 litre bottle to mix all my nutrients

I put about a quarter of a teaspoon in 2 litres I think that works out about right
Recommended parts per million of Magnesium for Cannabis, in flower, is ~48ppms.

My point was that it's hard to overdose when using Epsom Salt.
