I switched to my 150 hps at about 3 weeks from seed had it about a foot away, moved it to about 2 feet away after they started curling. Here are some pix...

what are you feeding, how much,,, soil type & additives,, pH , all info required to better help:wink:
if i remember right, it's seems the edge curl was a sign of a def. but can't think of which it was off hand,, ( P or K possabley),, try lookin through the Sick plant Sticky thread by MyNameStich,,, prolly find it in there somwheres..
I've had a few plants do that tho too,,, didn't seem to last loong, or cause any negative effects per-say,, but look through that thread:wink:

I have fed it ff big bloom and superthrive 2 times, then ff big bloom growbig and superthrive twice, then just water once after the transplant into walmarts expert soil with 50% perlite added. 2 days after the xplant I put the 150 hps in, temps remained about 75-80 except for 1 day the GF didn't turn the ac back on and temps were 90 for about 3 hours. I have since moved the light 2 ft above the girls. soil ph has been between 6 and 7, (using crappy ph test kit)
My suspect is marginal ph since its a leaf edge and not the whole leaf. They do look a little on the paler green side. Why are you feeding big bloom in veg mode?
I also get the same upward turning leaf edges on about 50% of all the C99 plants I grow regardless what I do to them. I have also seen it on other peoples C99 plants.
I would also invest in a more accurate PH tester since it will pay for itself with the results. Google Hanna Checker 1 and you should be able to find one for $25 online. Its battery operated and goes to hundredths [ 7.00 ] allowing for some serious anal retentive control of your ph levels.

why are you using the super thrive? just for transplant? ..they don't look big enough to have beens transplanted that many times yet..was there a problem.. other then the wrong soil wrong time thing?
... .LMAO verite
"serious anal retentive control.." 
I'm about to grow out 3 Webbed indica x C99's 
they're lookin great so far, bout 3 " or so each,,, i'll have to watch if they have this traight as they grow bigger. .. just hpin'' for all girls to start with tho

Verite... Thanks for stopping in! I have been feeding them according to the foxfarm schedule which is for the first 2 weeks feed 2 tbl big bloom( a worm casting and guano tea 0.01-0.3-0.7) and at 3 weeks add 2 tsp grow big. I have been feeding them half of the reccomended. Thanks for the advise on the ph pen I'm really into anal control... i mean anal retentive control. And I'm really glad you have seen this before on c99, hopefully its just a genetic trait.
cali grl... the superthrive I've been adding to promote new growth and side branching, and I think its been working, however i did go overboard on it.
I just watered again with plain tap water, and now the leaves have that just been watered droop to them. Thanks for your replies!
p.s. the pictures were taken under the hps so they look a little off color I will add some new pix soon.

First set of pics at the beginning of this thread show the leaves folding in reaction to strong light. Last set of pics show the leaves relaxing back after the light was moved farther away. It's very simple...... Nothing wrong with the plant, just watch that your light doesn't get too close.

thats the answer
Excerpt from the "Plant Abuse Chart and Photos by Nietzsche"
Magnesium (Mg)
Magnesium is a component of the chlorophyll molecule and serves as a cofactor in most enzymes.
Magnesium (Mg) deficiency:
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.
If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.
Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.
Figure 17
Bipedalhominid is probably right about the light stress, but just incase, you should add a little Mg to the next feeding.

Thanks everyone... I have moved the light about 3 feet above tops now. I have some ff grow big which has .60 mg, will this be enough or should I get the epson?

i don't know bout the mg def... there's no interveinal chlorosis at all.... thats talkin more whole leaf curl or "tacoing"

well i just added 3/4 teaspoon epson salts per gallon distilled water and fed it to them... Hope it doesn't fuk them up. I also added 1/2 dose of FF grow big. I have continued to raise the light, its about 3 1/2 feet above tops now. I guess I shouldn't have put the hps in there so soon. The leaves have been feeling kinda dry and thin... could this info help determine what the problem is?

Here is a pic of 5 hours after the feed... This pic does not look good I hope they bounce back!
