Hi Al, I missed a lot of things here that you have under control I think. These folks are so wonderful huh? This pic is from the problem solver. it shows Magnesium def. The write up mentions some things to use to make things right again.
Solution to fixing a Magnesium deficiency
Any Chemical/Organic nutrients that have Magnesium in them will fix a Magnesium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Other nutrients that have magnesium in them are: Epsom salts, which is fast absorption. Dolomite lime and or garden lime (same thing just called different) which is slow absorption. Sulfate of Potash, Magnesia which is medium absorption. Worm Castings, which is slow absorption. Crabshell which is slow absorption. Earth Juice Mircoblast, which is fast acting. (a must buy!! Has lots of 2ndary nutrients).
Now if you added to much chemical nutrients and or organics,( which is hard to burn your plants when using organics) You need to Flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.
Calcium may be involved but I think mostly Mag. For now everything is worked out! You might not need anything for the rest of the grow. The up potting works wonders. I don't want to add too much, Emilya and Amy and Shed and others have done all the work here. Just some more to add to the tools maybe.
Here's a pic of one from my last grow. She was root bound and recovered well.
