Ashamed to admit it but I meter tested the ppm of what I had been feeding the girl and it was around 3200. Way hot so the flush was needed. canna has a nutrient calculator and at .5 gal it says ppm should be around 900. So I am sure there are some heavy nutes still in the soil after the flush. Its been 2 days or so so I am going to feed her probably 500 ppm using RO water starting the next day or two. But when I put the nutes in the RO water it drops the Ph and I need something to get it around the mid 6 range before pouring it in. Here are some photos. Any suggestions?

Thanks to all for looking and commenting
GodBud Reviewed by GodBud on . Need Guidance on Ph issue Quoted from Site Adjusting pH Of Marijuana Grown In Soil A good way to stabilize soil is to use dolomite lime (calcium-magnesium carbonate). Dolomitic lime acts slowly and continuously, so soil will remain pH stable for a few months. Using fine size dolomite lime is important, coarser grades can take a year or longer to work. You can find fine size dolomite lime at any well stocked garden supply center. Dolomite lime has been used by gardeners as a pH stabilizer for many years. It Rating: 5
