Help leaves droopy

My father has been watching over my two plants over the last week while ive been out of town.. and they have been fine untill today! i just kinda taught him when to water and thats all. Today he sent me a picture of My 6-7week old plants. Theyre growing under a long 32 w fluoesent 6500k. just some miracle grow and no nutes. They have been looking amazing everyday but today they are extremely droopy! They havent been watered in a couple days but the soil isnt completely dry yet. Yesterday they were big and perky.. Should they just be watered..?

water when your pot becomeslight.to.thefeel, thats when youll know,
pick it up before andafter.the watering, take note in the weight diff
not trying to be a smartass, its how i do it

Pictures might help. could be a nute def. might need water, might need more light.

smokey has that shit on lock...plus smokey would never lie! Get used to being a human scale...usually when they droop its the plants way of saying "water please!". I don't finger my pots...just my ladies!

if the dirt still moist and the leafs are droopy it means they are not getting enough oxygen start right away for three days 12- 12 in the lighting then 6-18 all the way till budding time
