Is this Rust?
I believe the problem with the leaves is a fungus named Rust. Does anyone know anything about Rust? Too late for this plant, but I might be able to save my other plants. What's the best way to deal with Rust?

'rips' on leaves
Leaf damage between the veins only found it on two older leaves, had problems with calcium and magnesium deficiency early on, could this be a symptom of that or what else could it be? Haven't found any pests..

Cause of skinny new leaf fingers? Started a week ago or so but all the new leaves coming in have been had very slender/skinny fingers.. PH IS GOOD
Was doing research and what I found was either P excess, low humidity levels, light stress.. or just the Savita genetics? The plants are all in good health, growing fast and do not show any signs of deficiency aside from the skinny leaves forming. PH is fine, its living soil..
