I am growing in a deep water culture (Under Current System to be exact) set up and I just flipped it to Flower 3 days ago. My leafs are stating to yellow in the middle of the plan and I can not figure out why. I am running 10 lights with 8 HPS and 2 Metal Halide (1000w each)
1) Picture of the plants are included.
2) Growing indoor
3) Water is - "Filtered" from tap, reservoir tank (300gal), flushed it completely during Vegg to Flower flip
4) Deep Water Culture (under current)
5) 3rd Day into Flower (39th Total)
- I am running a 67 degree water tempreture
- 77 degree day 61 degree night temperatures (its GDP so they said Indica likes it colder, esp during flowering stage)
- The monitor is set to 1500 C02 PPMs but the reader reads between 900 - 1300 most of the time
- Current PPM reading is at 400
- PH trying to stabilize to 5.8 but it recently went down to 5.3 and i am working it to bring back up slowly.
