hiya, is it all the leaves or just some?
can you put up a picture?
the humidity is on the low side i think
never used tiger bloom, what is the npk on that, it seems like it is for flowering
watering daily? do you flood and dry? most soil growers recommend this
anyway a picture would help greatly
take care and good luck

I think it's the humidity, I split the grow area with another person, and he's stubborn and refuses to let me raise the humidity.
Here's the pic of the one curling

and here is the one that is stunted

and this is my overall grow

all the others are doing a lot better

If hes stubborn now about raising the humidity, imagine your problems down the road with him, especially since this is your first grow.there is no room for it.You want to get all of your mistakes out of the way and the only way to do that is through trial and error...Plants look fine, maybe RH is a bit low,,do you have a hygrometer?
