Weedhound Reviewed by Weedhound on . The Girls are Sick!! please help Good Morning, I am in dire need or your help. My girls where doing fine and then started to get discolouring on the leaves. This spread throughout the plant to where now some are completely yellow and curling on the ends in a few spots . I have flushed them once and also watered once using epson salts as first thought it might be a mg problem. I water every three days or so and use 1 ounce of DNA bloom 1 & 2 to five gallons of water. I use bloom fortifier once a week. I am in week four Rating: 5
