So Im about a month into my first dwc grow. The strain is purple haze. Using my well water which is 75ppm. I had upped the GH flora trio at 3-2-1 to 1000ppm with cal mag at 2mL/g and the largest fan leaves began turning yellow and had tips that started to curl down (Pic 1). The new growth at the top is also yellow and curly at it tips (Pic 2).
All the fan leaves seem dry and brittle but especially the 2nd largest set (Pic 3). It also looks like something spilled or dripped on one of these.The roots look fine to me (Pic 4). My humidity in my grow tent is rather low. So i had a humidifier in the tent keeping it at 50%..but have since shut it off and its back around 30. She's under a 400W HPS.Is this a deficiency or a toxicity? I can't tell anything concrete from other pictures online. I also see now that I probably planted her too low in this bucket and the leaves are touching the top in places.
Any help would be awesome.
