Email response from Seachem:

" To be completely honest with you, the only plant that we have come across that reacts negatively to Flourish Excel is Anacharis. Anacharis is a particularly sensitive species (known to be sensitive to high temperature, trace copper, formaldehyde etc.). Though there is no copper or formaldehyde in Excel, one person did notice that his Anacharis did not respond well to the product. I'm not sure if you have any of these in your aquarium, but if you do then perhaps try dosing the Excel a little less often. We actually have only received this complaint one time regarding the Excel, as most notice tremendous effects on their plants. Did you notice these negative effects only after beginning to dose the Excel? I ask only because some products that are on the market to re-mineralize RO water are sodium chloride-based and tend to melt the leaves on plants(Equilibrium is not). There are no plans to re-formulate the Excel, as we typically receive positive comments and also experience extreme benefits from Excel in our tanks here in the office. This is a completely unique product, in which the active ingredient mimics photosynthetic intermediates, thus minimizing energy output by the plant to take in a carbon source. If you could possibly provide us with the species that are not responding well to the product, then perhaps this will be useful information that we can pass on in case others have similar experiences. We appreciate your taking the time to provide us with this info, so that we may keep a list of particularly sensitive plants in order to help others. "

I heard of a few types of plants that do not do well with Excel, so I wrote them a email asking about this.
If anyone knows what species of plants do not do well with Excel please post here and give a description on how you know that it is from Excel and not just the plant condition itself.

If no one complains then it will never get changed for the better of "ALL" our plants.

If anything it would be nice to have a small list of plants that do not do well with Excel. Not every product is perfect, but this might help the product get to that point.
 
I think its good as is, most planted tank specific forums have done alot of time listing and providing feedback for Excel. I dont mind not being to grow maybe a few species outta 100, where I cant inject CO2.
 
vals and crypts typically have a 'melting' phase when first introduced to excel. After the phase wears off, then the plants grow as normal. It's best to 'ease' them into it, with, say a half dose every other day, and increase on a weekly basis.
 
I just started dosing Excel, and I've gotta say I've been using it 3 days and already see an increased growth rate in some of my plants. In fact one plant in particular has a lot of new growth, it's just exploded in the last 3 days.

My Val's where dying back all the way to the root, kinda defeats the purpose of fertilizing if you have to kill the plant before it will start to grow lol

What type of plants are they?

Not sure what they're called, it's the group of plants in the back center that are really doing well with the excel.

You see the four bright green spots in the lower front of the group? That's all new growth that's happend since starting to dose.

Actually there's 5, but one of my Cardianl tets is covering it. These are new stems.
