This run I've got eight plants. The last batch of plants were stressed - leaves taco'd/seeds in buds - so in this run I'm trying to eliminate all potential problems. Although, in the last run I think I had the lights too close.... Continuous improvement and all that corporate jargon.How many plants you got? Try measuring in detail for one plant, and for the other just get the pH close to 6.5-7 and see which performs better. I believe the more ''neglected'' plant would be healthier, but that's just a hunch.
