Help needed with cryptocorene parva

Hi i am currently having a nano tank that has a few cryptocorene parva, they were doing ok with a abit of algae growing on the leaves but i noticed that the new shoots were really pale, so i got some Seachem flourish (the comprehensive fert) and decided to dose the tank with some but one day later the yellow marking of the leaves were more obvious the upper picture is taken on the same day of dosage while the second pic is a day after.

dosage was followed and accurate so i am not sure what i did wrong, would appreciate help from you guys

I agree C.Parva is a very small slow grower with pointed leaves...]

I think that's Crypt Lucens but hard to tell from pic. Which looks similar to parva but larger.

It's a amazon sword or similar variety of sword plant. You can see the bud on one of them. The leaf shape and size is not a similar to any crypt I know. I have had over 30 varieries
tapwater and tapwater like this.

Looks like one of those Argentine Swords sold in a Petsmart tube.

It looks like you dosed one day and hoped for a change the next.I wish things worked like that but they move much slower.Continue dosing than check back in two weeks with results.Do you have adequate lighting and co2 or excel?

I agree they look like some sort of sword plant. However I suck at plant ID. Try posting an image in the plant section with a title ID please. Tinanti is a member that's very good at plant ID's. He seems to respond to most plant ID questions.

As far as them not doing well two things. You have them planted too deep. You never want to bury the crown (the base where the stem come out). Two, Flourish trace is basically only a trace fertilizer. You'll need to provide Nitrogen, Phosphorus and Potassium for them to thrive. It appears to me that the plants are lacking in those three nutrients. Consider getting some dry fertilizers it's much cheaper.

Yeah, this sort of looks like a chain sword (Helanthium tenellum) to me. Hard to ID w/o seeing the root system. But if this a crypt, the crown shouldn't be buried as @Zorfox mentioned.
