DO NOT try to lower the pH of MG soil; it comes out of the bag right on the money. It also has a tendency to go acid over time, but you have awhile b4 you have to worry bout that.
What you want to do is buffer your soil on the "up" side. Looks like you're in 1-gallon pots? Add 2 tsp of dolomite or calcium carbonate lime for every gallon of soil -- work it in about an inch. This will offset a decline in pH that will occur naturally in your soil as your plants process the nutes in it, but it won't raise it. Happy to give a chemistry lesson if you want to know why..
MG soil is great for growing weed -- don't listen to bullshit. But, it will burn little seedlings a bit -- it just has a little more nutes in in than they need. But then, so does Foxfarm Ocean Forest, which people fall to their knees over and pay $25 a bag for.
Just stick it out.. above all, don't overwater. They'll pull thru.
Good luck.
