I'd guess that the MG was the problem.
It's too hot for seedlings.
The replanting was a good move but quite stressful.

We usually love our first grow to death.
Cannabis is a weed, it thrives on neglect.
Very hard to diagnose without pictures but they sound over-watered.

Next batch, fill a container with dry soil and weigh it with your hand.
Then water to run-off and heft it again.
Remember the feel of it and use that as your watering guide.
(My memory is dodgy so I keep a pot of dry soil on-hand as a reminder.)

Not too wet, not too dry,
roots gotta breath
and that is why,
we mix da soil until it's right
with neutral PH and vermiculite.

Sorry, best I can do with the info supplied.
Suggest that you rat about in the everyt'ing link in my sig, while you wait for responses.

I'm new to growing and pretty much anything cannabis ;p Because of my ignorance for my first time grow I germinated 5 seeds 2 weeks ago and am now trying to figure these ladies (hopefully) out. Needless to say they are only now getting their third set of leaves and it's slow going! It's been a bumpy road and I've researched like a crazy lady but still have questions. First: Lighting was not optimal in the begining and probably still isn't. Using 4 CFL 100W daylight bulbs 6500K about 4 Rating: 5
