If so I don't notice a massive difference in the plants from the pics provided if anything they look more hungry in these ones.
Could just be the photos but if they are looking 10x better congrats.
Coir is tricky and if its not buffered it will take a lot of Ca and Mg from the feeds to satisfy its own cation exchange sites. then releasing a lot of Na and K.
Good coir brand buffer their coir and rinse it well, others don't. I love CANNA coir. they buffer, rinse and age/ferment it.
Best Of Luck with the rest of the grow!
