I may be putting Fox farm in the rear view mirror. This is my second grow in a row that I've struggled in flower keeping the pH up. I've been using FF for a long time, not just on recreational, but our veg and herbs. I run soil and coco grows, nothing has changed , not light, not temp, not humidity, not nutrients, etc. My plants in coco are perfectly fine, no new challenges. I contacted FF asking if they had made any changes to their soil mix, more or less of anything I could adjust for. They only replied that they assure me they use only quality products in the soil. That's not a good enough answer for me. Well I can assure them when I go to garden factory next week to up pot all our outdoor bucket veggies and garden plants in the greenhouse to sell I won't be getting a pallet of FF. I am to busy to be fixing pH drops every 3-4 days. Sorry to rant, I'm beyond frustrated.
