Bottom Leaves.. weirdness..

Yo.. i'm trying to figure out whats going on with the bottom leaves on one of my girls... i know that they fall off normally sometimes.. but ... yeah... what do you guys think?

needs more water possibly a nutrient problem but i grow all organic so i wouldn't know about nutrient problems

i see some white on them ..do you foliage feed

i dont foilage feed but i do spray them with water sometimes

Is the water tap or filtered?

What size container? How big is your plant?

16" standard pot size, tap water

When you spray, is it at night or in the day - coz the light will be magnified through the water droplets, although that normally burns holes in the leaf, if the whole things wet it could do what yours has and turn most of it dry.

I'm not sure what standard pot size is.
16 inch plant, may be getting rootboung if the pot is too small.
When a plant gets rootbound, the lower leaves begin falling off.
