I had a nasty iron deficiency recently. Some plants, like babytears,
showed a little deficiency. But the Amazon Frogbit made it VERY easy
to tell. Fast reproduction, but VERY yellow leaves. Started TMG,
within a week, frogbit leaves were nice green color again.
So, what I THINK I learned from this was that iron deficiency can be
detected by looking at the condition of new growth. Is this close to
I believe I've seen signs of nitrate deficiency too, with old leaves dying
away from the edges, but the leaf veins still green, while new leaves come
in nice a green for a while. But I'd guess that some nutrient deficiencies
just slow/stop the growth.
I guess my question would be: What nutrient deficiencies will just
prevent growth, as opposed to causing visual deformities in the plants?
