how big are the plants and the pot their in and how much water do you give them it is important to wet all of the soil and let it dry out i see where a lot of ppl just water right around the plant wich is not good you want the entire soil surface wet all the wat through the pot and let it dry to about 2 inches down into the pot poke your finger in to the second knuckle feel wet soil not time to water if it is a seedling it is possible that the sun is too strong and hot and may need to be put in the shade til it grows up a lil more. oh yea are they in pots or the groundI have had two plants die on me they are outdoors I water with tap water.They get plenty of sun just need to know if I am over watering
or is it somthing else.
I came across this neat little list that can probably help a lot of people out. If you like it check my post in the General area...I need some help!

my pots aren't huge to be honest, don't know the exact capacity.is your pot too small for the plant the soil does get a crust on tup that looks dry but just below its still wet tell about your plant age size pot size
well that could be it ive grown in small pots before and yea when a plant is a lil root bound you gotta water it more but i finished rootbound plants befor with no problem the light may dry out the top a lil too but is it still wet, poke your finger in a little see if you feel wetness or if you cant poke it cause roots are thick but yea that would be my guess without being their to see itmy pots aren't huge to be honest, don't know the exact capacity.
it gets dry on top so i put it down to my bulb (600W HPS) but it could be don to something else.
mainly happens to my larger plant which is a smaller pot so you could be right about he pot size.
