Im using Promix HP mixed with extra 30% perlite. I have been feeding at each watering to 20-30% runoff as told my hydro store guy. ive had some nute burn on each grow i've done. are my ppm's too high for the strains, or should there be intervals with no nutes?

You answered your own question. Since all your other grows have shown symptoms of nute burn, then your feedings are either too strong, too often or both. That much runoff is a waste of nutrients. Lower your PPM's to 500 and don't increase it unless you spot a deficiency. Since you are feeding often.

I always alternate my nutrients feedings with straight water feedings. I really don't think nutrients are needed more than once or twice per week. Remember the "Less is More" rule :wink:

Good Luck!
