Strange looking problem. Have you checked your ph? And are you feeding yet, or using straight water?

usually, you don't need to feed a plant so young, soil should provide enough nutes
i think the MG may have burnt the plant edges, it's got a reputation for doing that on seedlings
you probably want to back off on the nutes for the moment, a gentle flush with pure water may help
also depends on your soil, if it has fertilizer in it, it makes the situation worse, too 'hot' for a seedling

when i was using MG it was good, the it just turned on me. i also put the plants under light 24/7 could that be the reason. i did put it back on 18/6 cycle

24/7 shouldn't cause this. really looks like a ph/nute burn.
when you water, do you get enough outflow?
after 6 weeks it's possible for salts to build up in the pot if some light flushing isn't done. plant looks fine until the salt build begins to poison it.

that's pretty likely the culprit, watch you new growth for changes, if things are improving, the new growth will show it 1st
