Does anyone put epsom salt in the water you give to plants or foliar only?

I am growing with biotabs dry amendments in coco. I am following the biotabs just add tap water guide.

I use tap water that I put ascorbic acid vitamin c powder in to remove the chloramine in the water. I keep having what looks like magnesium deficiency in plants. I am not posting images of the plants in this post or asking about why the plants have problems I am only asking about epsom salt and how best to use it. I do not use calmag as the dry amendments in the biotabs are supposed to have what it needs for that. I have some epsom salt and I have tried doing foliar feeding a few times and it does not look like it is really working. I have looked online and it looks like most of the pages talking about using epsom salt for magnesium deficiency talks about spraying it but I would like to know if you can put it in the water you use when you water the plants on there.

I have 2 plants on day 22 that I water with only water and I give each like 1 half liter to 1 liter per day per plant. Would you recommend putting epsom salt in the water like 1 time per week or do you think foliar is better and how often would you foliar feed it to clear up magnesium deficiency on there?

I mix it right in my soils when I make them, so see no reason you couldn’t add it to your water.

Are you sure Vitamin C neutralizes the Chloroamine, brewers use potassium metasulfate or carbon filters to remove it

Thanks. Then you think you would be able to top dress the epsom salt for magnesium? I would rather do that than hand water it as I plan to use autopots on the plants. How much do you use per gallon in the pot on there? The ascorbic acid vitamin c powder was recommended to me on the forums and I posted about it a few times and was told by a few people that they use it for that and I read a few posts online and websites talking about using it to remove the chloramine in water and I think a few of the posts were on brewing websites and gardening websites on there.
