I started to see some signs of deficiencies but I’m growing organic. I added some fish and build a bloom from Build a Soil. After a few days I noticed it getting worse. I think it may be from overwatering and not letting the pots not dry all the way out. (I hate those plastic nursery pots). So I transplanted into bigger smart pots and added some premium worm castings. I fed them a beneficial tea using compost and worm castings too! Let’s hope they turn it around 👌🏼
What kind of water are you using? It sort of looks like nutrient burn because you can see the burned tips and the edges of the leaves are starting to show it as well. Even though you’re organic, maybe too many ppm’s In the water? Just a thought
@Nifty, I just use RO water. I use compost/casting teas weekly. I’m pretty sure it was from overwatering in plastic nursery pots. As soon as they hit bigger pots, the new growth showed no problems
