I grow in soil and have never had calcium issues before switching to LED. Why is this and will organic seaweed with micro nute and iron help or do I HAVE to get cal mag? It shows up halfwY through bloom.
when you switched to led di you leave everything else the same like temps and feed strength? try running a few degrees hotter in your grow and you prob need to raise your feeds.calmag can be a quick fix for some but its just a bandaid.i had to raise my feeds about 200ppm under led and my room temps went from 76f-78f up to 80f-82f now and the plants are happy again.I grow in soil and have never had calcium issues before switching to LED.

Why gypsum over kmag? See gypsum discussed more lately.Gypsum will take about a week to start working but it depends on your soil/moistur/heat. Usually it is prilled and will dissolve within a few watering. The sulfate will attach to magnesium in the soil and free up the calcium.
I would check the pH first though.
