That's the weird thing. The veins of the leaves are fine besides being purplish on som from the main stem to the leaf. Everything in between the the veins though feels like paper and are turning slightly yellow with some that have small rust colored spots on the edge of the lead. It's mainly from mid level up. But not every leaf, new growth is fine, mainly just fan leafs.green center/vein fading to yellow is cal mag should stop getting worse after a few feedings
