Feeding every watering (soiless mix)

Does anyone here use a soiless mix i.e. sunshine/promix and feed every watering? I was considering feeding 300-500ppm every watering insead of heavier feedings between plain water. Thoughts please

Good plan imo. Start at 300 and work your way up. The plants will tell you what they like and where the limits are, if you proceed with reasonable caution. cn
