boron poisoning results in crippled leafs (blistery structure) necrosis of leafs (brown spots at the edge an inside the leaf) root growth may be damaged too. Excess can be leached out in case of poisoning.
Anybody try boron? I never got around to trying it. I have Schultz orchid food fertilizer which is 0.02% Boron by weight. You're supposed to use 0.75g of the fertilizer/2.5L. I have Borax which I think is the decahydrate form. That would mean ~ 0.5mg of Borax per liter either as a foliar spray or soak. Seems about right from what I've read.

I use Borax, less diluted as a spray (double amount). A lot of plants react very positive to it. I had with lilies the most impressive and fastest reactions. No negative symptoms jet. Some plants got two or even 4 times the spraying. (Cephalotus and of course lilies f.e.)
Plants seem to cope with low light levels much better with this spraying. I garden with very poor soil and plants partly just survived. Now it looks like I had a green thumb.
Most cultivated plant look more vigorous, flower colours deepen, leafs look darker and have more substance (some exceed their size) and the stems are stronger. Flowers seem to last longer.
