The issue is more that MG soils have a lot of nutes and everytime you water more are released, and the plant uses what it needs and then the rest sit there and eventually make the plant unable to use any nutrients so the next time you water it is even worse...so on and so forth Here is what I would do for real right now...take 3 solo cups and cut little triangles in the bottom or whatever hole you want...I just find 3 or 4 triangles are nice for the shape of the cup just along the bottom edge...If you can get any perlite do so vermiculite or perlite...super important for draining any pot...anyway add the dry soil to fill about half the cup and then scoop in one plant for each, and then add more dry soil on top ...then leave it alone...the super wet soil that got put in with your plants will wick away into the rest of the dry and your roots should figure it out for themselves...get a fan and make sure those babies are blowing around a little...I mean don't make them bend over, but make sure they are definitely moving, and then put those lights side by side and put them above the top leaves, as close as you can get them without touching the taller one...
