At first look, I suspect they are overwatered. Which doesn’t mean too much water, but rather too often. How often are you watering them? Since they are in fabric pots, the easiest way to tell that it is time to water, is to lift the planter. If they feel light, water, otherwise wait. Always make sure the soil dry-cycles between watering.
If I’m right, they will recover, once their roods dry out sufficiently.
Thank you for the input! I typically water every 3-5 days depending on the soil, maybe I am not letting them dry out quite enough? Are the soil meters that measure moisture worth it or accurate?
I threw mine away. I found that the weight of the planter works well. If you’d rather find the correct schedule, one method is to water, wait for wilt, then subtract 12 hours. They recover from underwatering much quicker than overwatering.
The white spots are diatomaceous earth; I struggled with spider mites on my first grow and I’m desperately trying to prevent them after dealing with them the first time. I had to invest tons of time and money into getting rid of them. I obsessively check for them with a magnifier now so I am fairly certain there are no pest problems at the moment.
