I'd like to try Milorganite sometime, but it's not available locally and I haven't found it available when I've remembered to look for it in the larger cities. I may be able to order it online and have it shipped to a store that's near, though. I haven't checked for iron here. Generally this area isn't deficient in available iron so the local stores may not carry it either, but maybe. I guess the iron pills would be available at the drug store? The plants do look like they suffer from chlorosis to me. Some of the leaves on the larger seedling show it as interveinal on the older leaves with the new growth coming along smooth and pale. On the little one, it's the opposite. The older leaves lose even the pale green and turn creamy white while the new growth is a very pale green and that plant has never had any interveinal chlorosis showing. I'm going to try the iron. I had thought of that, but since the potting medium is mostly purchased material comprising pine bark and potting soil (probably Miracle Gro but occasionally I've picked up some Bacto) it didn't seem as if that would be too likely. I would say it can't hurt, but when I lived elsewhere and some plants needed iron it was highly beneficial to some that needed the iron and lethal overnight to others. I actually eliminated a noxious weed in the yellow lawn using it, but drifting mist also nearly eliminated a couple of plants I wanted. It was miraculous on the yellowed plants. I used it very carefully after that.
