Good morning! 🌄

Have seen black dust before, but all of a sudden it got bad.. Help

My son grows plants 🌿in a tent and the tent is typically zipped shut unless he is tending to them while the grow light is turned on so as not to disrupt the dark hours. His dog always has to be involved...he has developed a liking for eating the leaves. Because of the summer heat, my son has had to leave the tent open. Yesterday morning when they got up, as per their routine, he asked his dog if he needed to go outside and the dog excitedly ran off. When my son came out of his room to head downstairs, the dog was nowhere to be seen so my son called out to him. No dog, so he called out again a little louder. The dog came prancing out of the plant room with a mouth full of leaves and his tail wagging happy and proud! When the dog first started eating the leaves, they were only the one or two my son offered. I said that one day the dog was going to help himself and yesterday morning, he did just that!🤣🤣🤣

Learned a couple of macramé knots on YouTube and made a trellis hammock for one of the pumpkins!

For Chad, any idea what's causing the discoloration in our (older) TG plants? The pH has been slowly creeping up, but TDS is stable, and water level is as well. This is our kale, growing about a month and thriving. It's just begun this brown-ish presentation. Problem?
