I'm having a problem with my girl. I have one Sativa and six Indicas. They have been in flowering for about four weeks. They are in a 8x8x8 room with 72 23 watt CFL lights. I have been using .5 mil Dyno-Gro Bloom 3-12-6 and .5 mil Botanicare Cal-Mag. The first three pictures are of my sativa. Its stems are bending over and weak the leaves and turning up and yellow on the ends. And it is not maturing slow. The next four are of my indicas there leaves are light in color and the ends are bending over and turning brown. Don't know if this normal thing to happen a four weeks into flowering. I can use any help I can get, since this is only my second grow.
