Leaves issues !

if the soil/medium is still damp and they are wilting its an over watering issue. If its bone dry its lack of water but generally speaking you can let the medium almost fully dry out before wilting becomes an issue. So dont be shy to let them dry out a bit more ok. in fact some commercial growers have said a few dry spells during flower can speed up the flowering process- ive been going easy on the water to my girls this time and so far it does seem to hold some truth. around week 3 and week 5 you do a light flush and then you want to let the plants almost fully dry out until they just start to wilt and then give em a strong feeding after that- like 1.8EC and it can take a week off the total flowering time. So yeah, let em dry out this time a bit more then you would normally do and they should be fine.
