I grow in Promix and I usually water daily, or every other day. The plants get pretty dry and can start to wilt if over 2 days (using 5 gallon buckets). I typically water a gallon/day, but considerably less when plants are small. I feed every 12-15 days, which eliminates salt buildup. In the Promix, I have added about 15-20% compost/manure (for micro and macro nutes), a handfull of time release fertilizer, and a handfull of wood ashes. This keeps them fed but on the lean side. I don't see any nutrient related issues and use 20-20-20 nutes, and a similar blooming mix for flowering.Def stains on the bottom of the pots. I water when it's almost dry.
It works great and is consistent. Great results for 30+ years.
