What's WRONG with my plant

My plant looks healthy but the leaves are starting to curl inward....does anybody know what's going on? The plant is 3 weeks into veg... Not sure if nutes have anything do with the problem but I have used mexican bat guano, liquid karma, and canna substra vega, rhizotonic, cannazym, and cal-mag (all in correct portions since the seedling stage). BTW I'm using a 1000w MH system and all my other plants are doing fine

When i've seen leaves curling upward like that it was a lot of times due to heat stress...

The leaves will probably start to yellow a bit (the onces that are curled up) in the next day or two.. IF... IF it's heat stress, it might not be...

Just keep an eye on them and update us here on the boards about the progress... whether it be good or bad...

Looks like heat stress to me, how close is your light, what is the light, temp and ventilation.

my handy dandy diagnosis page says for leaf curl, check the following:high light amount, too hot, too cold, low humidity, pollution, pests. Rule out the ones that dont apply and fix the ones that may be the problem.
good luck

my lights are approx. 2 feet away from the plants. I can't give a exact temp because I dont have an instrument to read temp as of yet but I do have a fan circulating air very well within the grow room

the leaves curls up 4 days ago

Do you have an exhaust fan to pull hot air out, you defo want to get a miin/max tempo gauge.
