Impressions about plant
Plants still look great. Skittlez is the biggest, but rotated all plants to put the smallest one in the middle of the light. Had to move the light down to roughly 10" to get a reasonable Lux/DLI reading. This thread has been master informative - https://support.ilovegrowingmarijuana.com/t/start-using-dli/64987/481. Realizing this light is way underpowered....maybe good for one plant, but barely adequate for three.
Also added a cheap humidifier with an Inkbird controller to try to keep the humidity in a better range, checking against this VPD chart to see if I can get that right - https://vpdchart.com/
Still have discrepancies with my meters. If I go off my Lux meter, avg is 45000 which is roughly 700 PPFD. If I go off of Photone, my avg lux is about 33000, or about 530 PPFD.
The app has my avg PPFD at 325 with my best DLI at 46 in the center.
Soaked the plants with 1/2 gal rain water on Saturday before moving the lights down.
Gave plants another 1/2 gal rain water with nutes on Sunday.
1/11 - Gave another half gallon of rainwater...much, much less runoff than just a few days ago. Plants seem to be bulking up more than getting taller.
1/13 - Gave a full gallon of rainwater plus nutes today, and run-off was similar to 1/11...root structure must be growing. Also took some TDS readings. Rainwater sitting at 22 ppm, and after addition of nutes it was 976 ppm.
