Few things wrong here; first not enough information.
2nd; if I were you, I would get that plant out of that big pot pronto before you end up overwatering your plant... This is a big mistake new growers make is putting a small plant into a big pot so they do not have to transplant; not only is it lazy, but you get what you give.. meaning you be lazy you are going to end up having trouble down the grow.... big pots small plants are one of the easiest ways to over water; because the plant has not rooted the pot and water sits in areas where the roots are not at causing the areas that do have roots to remain too moist and then you end up getting droopy plants, then locks out nitrogen and the lower leaves yellow;trust me... you will end up over watering it; not to mention putting a plant into a big pot stunts it's growth, cannabis likes to root the pot before it hits it's growth spurt; around 75% of the pot needs to be rooted before doing this... I would put that pot into a 1 gallon size pot MAX.....
I need more inforamtion about your grow... what soil mixture is the plant in? what wattage of HPS are you using and how close is it?
what are your temps and humidity? Canopy temps?
It may be heat stress, but with the HPS light on I can't tell, so can you please take another picture of the plant? The hps hides issues when trying to diagnosis a plant.

thanks for the input.
putting the plant into this pot wasn't the lazy option- believe me mixing all this soil in with the lime etc took hours. These are feminised seeds so seemed like a good option. I wanted to give them plenty of room for the roots- last time I ran into probs with plants in small pots, and had none with the plant in the bigger pots.
Plants are two weeks old. They're under a 250 w HPS. temp is 20-25, good ventilation. soil is a mix of good quality compost, small amount of perlite and vermiculite and the lime.
My main concern was that the lime might be causing this...as I said 5 oz in 5 gallons. This is the recommended amount though isnt it? This amount stabilises the ph at 7 from what I've read.
I know I need to get a ph test.

Normally you are supossed to use 1 cup per cu feet of soil....Which is roughly around 12 gallons of soil...... 5 oz in 5 gallons is a lot.
That cupping looks like they are getting dry heat, have you tested the temps... for small plants like that even a 250 watt hps like that can cause issues, how close is your light and you did not answer my questions........
That is why when the plant gets to big for the pot you change the plant into a bigger one. 12 in tall plant to a 1 gallon size pot MINIMUM.
The leaves are cupping upwards; looks like to high temps for too long of a time; what lighting cycle are they on?
That is very true core; but I always have to assume the grower does not know how too, cause if they did know; most of them would not use big pots cause of the hassle

Hi everyone,
this happened to only one of my plants in a grow of six. And happened on only a set of leaves not entire plant.
The plant is fine, and i never saw it since. I believe it just happened. Prob heat stress. I know your temps are fine. I bet it happened as soon as you put them under that HPS and they where under cfl before.
i'd say don't worry. Imho work your grow as it never happened ...
Good luck

They're under a 250 w HPS- light is 18 inches away from plants. temp/ canopy temp is 25 degrees. soil is a mix of good quality compost, small amount of perlite and vermiculite and the lime.
I came across the reference to the 'cup' of lime before- didnt seem exactly scientific.a cup in 8 ounces right- for 12 gallons. Would too much lime cause the cupping? Do I need to bin the soil?
I have grown cuttings out in large containers before (not this big though) with no problems. I'd prefer to avoid having to change the soil.
