Mg deficiency or Rust fungi!!

WW, isn't that what I wrote?

sorry, I guess I misunderstood.

"Plants need calcium for cell wall development and growth. Pathogens attack weak cell walls to invade a plant, and stronger cell wall structure avoids this. Plants need calcium for enzyme activity, metabolism, and for nitrate (a useable form of nitrogen) uptake. Calcium and phosphorus are often found together. Plants need phosphorus to grow strong and healthy, for moisture regulation, photosynthesis, respiration, and metabolism. Weak and spindly plants often indicate the plants are not taking up enough phosphorus and calcium. Of course, there are other factors affecting plant growth such as pH imbalance, high sodium, over- and under-watering, poor drainage (humus can help with this), lack of oxygen (from compaction, and lack of organic material), and temperature stress. The ratio of calcium to magnesium is said to be a factor, but I have seen no research indicating such when considering the calcium form necessary for best plant uptake. Too much sodium in the soil can also bind up calcium and make it unavailable to plants."
Plants need calcium, too

The cell damage can also start looking like OD'ing on heavy metals. I haven't seen a calcium def. like that in quite a while though. But perhaps the nutrients are salting-up the medium, locking-out the 'available' calcium in the soil. Do you ever flush the soil?

did anything help this situation? CalMAg?
