Well i am trying to revive my 4 blackberry kush plants and one sour desiel. I have purchase hygrozyme and have added it today. I changed my reservoir and my nutes are still at 1/4 because i have recently changed reservoirs because my old one had glue in it and harmed my older plants. I have around 428 ppms and a 5.9 ph. I have added fox farm grow big, big bloom, 3% peroxide, and 15 ml's total of hygrozyme because it works with h202 products. I hope this combo will bring my plants back. Oh ya i am also misting them with ph balanced water and with 2 drops of sea kelp in it. THC Labs does the same thing to water there plants
