Over the last few weeks I determined that the plants were not going into flower on their own, So swapped over to 12/12. I'm hoping I can switch back to 18/6 but I not sure if I want to risk it. going back to veg. Will update next week on whether I switch back or not. Had some root rot issues during late veg, which may have slowed the flowering I assume. Added in Hydroguard and root rot was gone from the first day using it. Highly recommend.
