Leaves acting funny...

I dont have pics at the moment but lets see if someone can understand this.

I checked the growfaq and saw nothing like this.

The sun leaves have curled up, not the tips but the length of the leafs fingers. almost like they are trying to roll themselves up like a paper twisted for a joint.

I gave my 2 flowering plants a 2/3 strength mix of flowering nutes. only the one plant, the bigger of the two is doing this.

Nute burn. Sativas are notorious for doing this and many indica varieties are very sensitive to fertilizer. Pics would be a great help though as ph can cause twisty leaves too but its easy to tell the difference.

Sounds more like a tempature flucktuation.if the leaves are like the first set of leaves that you get when starting from seed.nothing to worry about just keep a close eye on the temp when the lights are of if you live in the uk i would advise haveing lights on at night rather than day because its cold at night and a little warmer durig day.

pics would be helpful, but does sound like heat. what color are the leaves.

Over-fertilizing - the most common cause of leaf cupping aka leaf margin rolling, leaf margin burn, and leaf tip curl/burn is the overzealous use of too much plant food in relationship to factors such as plant vigor and rate of growth. The first unit of a plant to show moisture stress is the leaf at its margins and/or tips, reflected by margin rolling (cupping) or burning. A hard, crispy feel to the leaf frequently occurs as well, as opposed to a soft and cool feel of a happy leaf. When you have a high concentration of salts in solution (or in the root medium) compared to lower salinity levels found in the plant?s tissue, water is actually drawn out of the plant across the root gradient in order to fix the ppm imbalance. IOW, this is a natural, osmotic response that serves to equalize salinity levels on both sides of the root?s epidermal gradient. Back off on the amount and/or frequency of plant food. Too much plant food can also burn the roots, especially the sensitive root tips, which then creates another set of problems. Note for the bio folks - as soil dries, the concentration of the remaining salts rises further exacerbating the problem.
