Looks kind of expensive. $14/liter, which dilutes to 100 gallons. MiracleGro is $10/5lbs, which dilutes to 300 gallons. MG is 24-8-16, while this stuff is only 6-6-6. Not clear what is special about it otherwise.

6-6-6 is fine for seedlings. Would not want a ratio of N that high in the MG that you cited (but there are probably other formulations of MG).

For seedlings, I use a 50% mix of MG. That works fine. If you want, you can dilute it more. It's really up to you what strength to use. That's true with any fertilizer.

indoors.. right???

i would say proper light intensity is more important than fert ... and im pretty sure.. you have that covered.. right???

after that ... i dont go in for much snake oil ... 6-6-6.. 6 cubed.. is 6 cubed.. is 6 cubed ... cheapest is best ... imo ... the numbers dont lie... nothing else matters ....

price doesnt impress me ...

when i did seedlings ... i had bleached out gallon milk jugs.. with just enough blue kmart fert in the water that it barely turned the water blue .. and used it for every watering ... it was.. and still is.. the 5 pound plastic jug my dad bought in the 1970s .... lol .... wonder if the price tag is still on it ... [it was less than a 1.4 teaspoon per gal ...]

I also don't buy anything other than the most basic 7.7.7from the ag.store and, like Ken, I do a really dilute mix for every watering as I will forget until the plant looks miffy...at which point, there will be a noticeable decline, which is always detrimental for annuals. I have spent more £££ on organic seaweed ferts and the whole range of brands beloved of cannabis growers. Waste of money, tbh. I avoid piddling bottles from a garden centre and buy wholesale farm quantities, every 3 years or so.
