Crispy end to leaves and curling up

[ZxPwn420]

My plants are growing under a 125W CFL with SunMate Powerplant Reflector. They're almost 2 weeks and the strain is Super Skunk (Nirvana).

The tips of the leaves have turned crispy on both plants which I think is due to when I was transplanting them into bigger pots, I cut through some roots. The first 5 pictures are of the plant which the leaves are curling upwards and are looking skinny. The last 4 are of the ones in which lots of roots were damaged however, both plants has improved since then.

Any ideas?

From my research, not experience, so others may want to chime in with other tips but this sure sounds like lack of magnesium to me. Following is a quote from http://www.marijuana-seeds.net/Thanks-ThankYou.htm

"
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.
Notice how in Figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil."

Just looks like typical nute burn to me, are you using nutes or any nutrient rich soil?

Yeah, i'm using MiracleGro nutes and i'm not too sure on the soil, i'll check it tomorrow.

wooo, tell us what he won?!

Is this because i'm using nutes this early? I was told that feeding them from start would help them with root growth and stuff =/

you should start on veg nutes after they have established a few set of nodes.

your problem is either too early nutes or too heavy of a strong nute (MG).

i would only feed them with 1/4 strength solution and plain water every other feeding till their big.

Maybe a little heat issue...

yea i agree it seems to be a heat issue but then they were talkin about the MG and so on .....

Heat stress , nute burn .
Lay off the nutes for a few weeks , very dark green leaves is an indication to too muck nitrogen .
Also move your light up maybe 3 inches and after a few days if leafs start to settle down and just hover , lower your light a inch .
If i was you i would also add more soil to your pots and also add some perlite in the mix aswell , so roots can breath .

Yeah u also have a little curling of the leaves which I didn't see b4 = heat stress!

UPDATE

One plant has improved vastly. I flushed both plants, and did a quick spray with some Epsom salt + water solution, a couple of days later i seen some improvements

Last update:

The plant that survived is going great after using epsom salts!
Thanks to everyone!!!
