Hi guys,
I'm growing for my second time to handle my medicinal needs. Unfortunately, it has not been smooth sailing. I'm running a recirculating system and my growing medium is Grodan rockwool cubes. I'm using the General Hydroponics Expert Flora Series. Fortunately, I have a good connection for clones. The clones are treated for mites and mold before I begin to flower. There are no mold or mite problems. There is a dehumidifier in the room and temperature is always ideal. I run CO2 at 1000PPM.
The first two times I've tried this system, I had about 15% of my plants begin to show stress in week 4-5 of flower. They begin to look like they're drying up. The end result is a whole plant that is yellow and dry (including the flower). The strange thing is the flower still has crystals and smells good, but it has completely yellowed. During my first grow, I flushed my plant when almost completely yellowed over and gave it water. The odd thing is some of them kind of came back and started to green over.
The problems starts with 1)plants start looking sad 2)leaves start to yellow, leaves closest to the actual buds yellow first 3)the buds and stalks turn yellow, almost looks like straw or hay
Any idea what could this be? Is it hard water? Over feeding? Please help as I cannot figure this out. I've attached a couple pictures. The one with green is when these plants first start to show signs of stress. The second one is almost when the plant is ruined.
Thanks so much for the time.
