Good day,I am finishing off a strain of blueberry feminized and a pineapple chunk and I am looking for proper ph levels for both strains they've got approximately 1month to go and I don't want to stress them if I can help it. I am useing a top feed dwc system with two 400 watts LED, I started out with one and added second one three days ago. Hope this information helps. Thank you, Narse
