Ok so, lets assume the LEDs cause magnesium issues. And you are using epsom salt. Are you dissolving it fully and watering 1g each water? You could try to dissolve some and use as a foliage spray. There’s is a proper ratio for all nutrients, including calcium and magnesium, you have to make sure to have the proper ratio so it is all absorbed properly.

Yes, I am using epsom at 1g in feed. Should I, instead of putting it in the feed, just foliar the mag? Or should I cut it in half and put half in the feed and half in the spray. Or should feed and foliar 1 g each?

Are you so sure it’s magnesium? According to the chart I’d say potassium. And if your nutrient ratio is indeed 321, NPK, then maybe you are low on K.

I was thinking it's potassium but not sure. I've asked in other forums back when they started show up and they pointed me to a magnesium deficiency. Confusing. I have some MPK on hand wasn't thinking I'd be using it so soon. Hear 2nd week of flower is when I should be adding it to the feed.
