Do these ladys look okay need experienced growers!

Hey guys just wondering if these ladys look the right size for 2.1/2(almost 3) week cuttings and if anyone can tell me whats wrong with them...

what are your temps like? that curling is usaly heat-water realted i had it once. what soil are you useing? lights? ph? red stems usaly a good sign of some defincey starting or crazy temp change.
let me know
much love

i see roots at the top of your pot maybe the soil isn't loose enough and your getting twisted root growth. i dont like the way your soil looks is it a potting mix blend?

There in canna coco+ then placed under a 600w Hps with 8" outtake and a 5" intake and 2 passive intakes(temps fluctuating from 27 to 34)and Humidity 40-50%.I am also using the cana coco nutrient range.PH is 5.8 run off around 6.0-6.2..

the top growth is fine thats what counts, i would be worried it that curling keep continueing up the plant, as said above it looks like heat stress or transpiration stress...make sure your fan isnt directly blowing on the plant/foliage 24/7 and make sure your light is at the appropriate height so that its not drying out/burning the foliage/plant.if u need help pm me

the redness in the stems can be a deffiency but i wouldnt worry about it unless u can actually see the plant stuggle in anyway like, slow growth , discoloration etc ..

Thanks guys ill monitor the temps and keep you guys posted on the results thanks again peeps.
