What’s appening to the little northern light auto?

Looks like a ph issue. Are you checking your ph before watering as ph perfect nutes really only help stabilize your ph. You still need to check the ph going in and the ph of your medium. You need to water enough that the entire planter gets saturated as well. Water to runoff. Fabric planters channel the water like a river once their full of roots, that leaves dry spots inside your planter. Dry spots, dry roots, brown spots on leaves. They can also look over watered when their under watered. Go easy on the nutes as well, less is best, only give more when they look to pale. Cheers
