One month and 3 weeks old with some problems

I have two ak-48 plants that are one month and 3 weeks old respectively. They are given ph adjusted water with a tiny bit of miracle gro seedling nutrient solution in it. The lights are 32 w flourescents. They are on a 20/4 light cycle. Recently the big old leaves started browning at the edges and started to show lighter spots. This is now starting to spread to the small new ones. The leaves also curl slightly upwards. The grow is still very good, but I can see that the plants are not feeling 100%. Judging by the pics, what would be your best guess? They have been treated for magnesium deficiency with epsom salt but it doesn't seem to fix the problem. They are growing in rockwool, by the way, and yes...I am a first time -grower

it could be light burn do you mist your plants? water droplets act like a magnifying glass, you know what you do to ants with those that might be happening to your plant

Is that foil you using for reflection? If it is get rid of it. It causes burn spots on plants leaves. How much miracle grow are you giving the plants?

you don't want light hitting underneath your plant just the top. and if you just want something to cover the soil use a paper plate. and as of the yellow spots. it looks like N def.

They have just a little nuit burn not much, let them really dry out then just give them water that has been sitting for a few days, in the future only feed every other day, so feed, then just water, feed, then just water etc etc, but always make sure the soil is almost dry top and bottom, get them hungry.
And going by the pics you are also spraying them, id stop that.

I agree.. looks more like a deficency than nute burn.. at a month.. yeah.. bout time for nutes..just ease them up and make sure you don't go overboard and burn them.

So I have give them nutes for a couple of days now and it seems the problem has stopped expanding. So far no reversal, and I am thinking some of these leaves are too far gone to get back to normal. Going to get some hydro specific nutes today, and also specfic for mj. Will See what happens with that.
