Hey guys im about to start flushing after 1-2 days and currently im using RO water and on every watering im adding first potassium silicate and then calmag and nutes but when im flushing should i water them with pure RO or can i ad only potassium silicate or both silicate calmag
When I flush or leach at the end it's water only. I cut silica off at end of week 3 or 4.
You can add cal mag, I do a water with calcium sulphate next to last week and then calcium carbonate the last week, instead of using calmag.
Hope this helps
