The plants in my grow tent just aren’t thriving with curled leaves that are either yellow or red. When they are repotted they’ll thrive for about three weeks before regressing. I’m using pro-mix potting soil and Espoma fertilizer. I’ll add a small amount of either Plant Tone or Bulb Tone to the potting soil, basing which I use on the plant’s need for nitrogen. Additional fertilizer is added with liquid Espoma Garden and Tomato fertilizers. The water is from a well and the same water that is used for houseplants. The houseplants are doing great. Light on temps are 70 degrees light off temp is 60. There is a layer of styrofoam insulation board under the tent to prevent the concrete slab underneath from cooling the pots. Lights/exhaust fan on humidity is ~30% and the lights/exhaust fan off is 60%.
I had previously used a 600 watt HPS and had no problems, but I don’t see why the LED light would be the problem. The model of light I am using does not have UV.
The symptoms point to a phosphorus deficiency, but the fertilizer I’m using has that covered.
Plants in the picture are lemon grass, mint, chili pepper and lemon balm
