2021 Spring/Summer OD Hydro Autoflowers

Early in the week I cycled the tank and stabilized PH to 6.0 with Nutri+ PH down product (35% Phosphoric Acid) and it seems to be working quite to settle PH of the solution. Only a few drops were needed to bring PH to 6. My starting water is 30 PPM city/municipal water at a working PH of 8.5-9. CNS 17 seems to buffer down to 6.2-6.5 I also added the following per 10L: Canna Cannazym - 20ml Canna Bio Rhizotonic - 20ml The plants are looking generally well but some of the older leaves are showing signs of decay. I will probably prune off these areas next week. I will take some pictures of the root zone next update.
