Hi. I am having problems with my plants in coco. Leaves are dying off, showing mag deficiency. I was adding calmag, but problem did not go away. I have checked run off ph and it was 6.4 and even 6.6 on some plants. Yesterday i have flushed them with nutrient solution at 5.7 until run off was 5.7-5.8. After 12 hours I have watered tgem again at 5.7 just to collect and check some run off. It was 6.4-6.5 again. I am using canna pro coir and canna nutes plus calmag and ro water. I have made nutes solution in the morning and ph of it was stable. Ph meter is calibrated. Any help welcome.

Coco has a tendency to have a ph around 6.5 and that is good for your plant. When your run off is above 6.8 then you might want to get some low ph water to flush out the excess. Let her dry out. Next feeding, add some cal/mag about 200 ppm for veg. 5.8ph is for hydro. 6.5ph is for soil.
