Top leaves curl after watering on some plants?? help please

I am using FF OF for soil, they are in 5 gallon pots, 6 days into FLower.

Violator Kush is fine, Red DIesel and skunk get droopy on the top leaves after I water.

I water every other day, using 2 bottles of water, usuallly until the water comes from the bottom of the pot.

There is a time when the diesel and skunk and big bang get droopy, then I water and they spruce upp. Only they usually have the top leaves curl down after watering. I dont know if this is from genetics or what as some of the plants dont do this and are all fed at the same time and feed.

Any help or know how on the subject would be very appreciated,

Thanks

the pictures on the right are of the other plants that don't do that

no information on this one

Its nothing to worry about my friend. some plnats do this and some plants dont, i thinks its just the shock of the water hitting the plants roots. my plants do this but not just the top leaves but all the leaves from half way up the plant. and then about 2 hours later they are reaching for the sky again. you can try watering them with warm water to avoid stress it might help
