Some of you might be following my grow journal, but long story long, here’s the problem:
Over the past few days, the leaves of two of the four plants have started getting yellow patches and the ends of some of the leaves are getting a tad crispy.
Root production is still very good, they’re filling out their buckets nicely. They just got a water change and new nutrients. Even the healthiest of leaves on the plants were feeling pretty dry, so I added a humidifier to the room. Running on high. Spout is about 8” away from the plants with a fan blowing the cool mist just over the canopy.
Room temp: 75 (day), 69 (night)
Reservoir temp: 68F
Humidity: was averaging around 48%, now around 65-70%
Humboldts Secret nutrient lineup
Still running the same lights (2000w full spectrum LED and 48” 6xT5HO). I highered the LED to about 20” away from the plants to compensate for their extra height. Only feels ever so slightly warm on the back of my hand at canopy height. No perceptible risk of feeling uncomfortable due to heat.
Please help with any more ideas you might have with setup modifications or remedy procedures.
Thanks so much again guys!
Ps. Here’s a quick pic of the grow system as of yesterday:
