Have an issue with my plants it could be a calcium or magnesium deficiency although I do use Fox Farm nutrients. And growing soil. I think it may have actually been heat stress or light stress. But my question is if I use calimagic calcium and magnesium could that be harmful for my plants if that's not the issue? I have heard that it will not affect my plants if I use this and it's not the issue but obviously will help them if it is?

Hi @Yankee01 and welcome to the Forum! 
I saw you just give a very intelligent answer on another thread so I know you have a good idea what is going on.
In the amounts it is given in most of the calmag products it is not dangerous. The danger comes from having too much mag in the soil... it can easily lock out other nutrients, but these supplements and their low dosages are safe in a maintenance dosage all through the grow. Send us a picture and let me confirm for you what the symptoms look like.

the ones in the red is when I switched it to LED after my metal halide may have been too much for a 4 by 4 by 7 foot tent. What do you think?Hi @Yankee01 and welcome to the Forum!

yes, they look a little light stressed to me too. 1200w of mh on young plants is a bit much, especially if you were any closer than 36 inches.
