Hey Tankerous - like the name.
In my experience, growing under LEDs can seem to require a plant to consume more Calcium, and perhaps Magnesium as well, though its important to try to keep the two separate in strategy.
If you have a solid organic mix and enough of it (often its recommended not to go smaller than 7 or 10G for a full term plant), you shouldn't really need to add more top dressings, teas, etc than would be required under any other light - to my knowledge. The plant, being in control in a LOS scenario, will be able to, using root exudes and soil microbiology, adjust the mineral intake to whatever end is required. As long as the mineral balancing is within reason, and the required nutrients are present, you'll be on autopilot.
