Leaves curling up, is it lack of nurtrients?

im currently about 2-3 weeks into flowering. i was having problems earlier with my leaves drooping and curling under, so i transplanted it into a bucket with some really old soil from a horse farm. since i transplanted it, the leaves arent drooping anymore (except the bottom ones). now my problem is, the newer leaves on the top and ones on the little branches are starting to curl up along the sides of the leaf fingers. im not using any nutrients at the moment because i havent been able to pick some up. someone told me it could be lack of nutrients, but i want to know for sure.

looks kind of like heat stress...give us some details

well right now i have a 40 watt cfl on top and three 23 watt cfl's on the bottom, so the entire plant gets light. u can see it in the last pic.

Agreed.

Make sure there's a fan circulating air.

Could be salt build up or possibly watering issues. I don't think that the CFL's heat would be enough to give the ladies heat stress, I may be wrong though.

i was thinking it could be watering issues. but im being carefull not to water to much. i water about every 2 days and i use tap water that sits in the grow room so its stays room temp. am i doing anything wrong with that?

im going to put a small fan in there and see it if helps. right now i have a small computer fan bringing air into the grow space and a few other computer fans on the bottom of the grow space circulating the air. but im thinking there not powerful enough.

Could be praying for calcium.

just recently put a fan in the grow closet. its blowing just enough that the plants leaves slowly move. the fans been in there for about 2 days so im sure the temperature lowered in there. so it cant be heat stress, the leaves still look the same. there all wrinkly looking, especially the little leaves on the smaller branches. it must be hungry for nutes, im STILL trying to get my friend to bring the powder nutrient shit i need.

The salt concentration is too high in the soil and is burning the plants. They need to be transplanted into a good potting media, not put more fertilizer salts into the soil. Make sure the buckets have enough drainage holes in the bottom to prevent the lower half of the soil ball from becoming too soggy.

that may be the problem because i forgot to put holes in the bucket before i put the plant in it. but what i dont understand is, my friend has another plant in a bucket but his bucket has holes and his littler leaves are doing the same thing as mine, but its not as bad. his bigger leaves look fine. im going to put some holes in the bottom of my bucket and hopefully thats gonna fix the problem. after i put in the hols, the salts in the soil should wash out over time right?
