Hey there Valhallas, so I've been trying to find the actual ingredients of flawless finish but I can't find them. If I remember correctly it's got two things inside 98% is water and 2% is hydrochloric acid which is the flushing / chelation agent. Basically if you use too much of it it will dissolve your roots , but if you use it only once it basically will act like an amino acid boost chelating the existing nutrients in the soil and giving the plant a healthy dose of chelated nutrients. Thing is though, it won't keep acting nice like amino acids might, it will kinda eliminate nutrients in the soil. If you feed again you'll need (want to?) Add another chelation agent because the hydrochloric acid will have kinda killed off all that helpful life in the soil. So is it safe to feed again? Yeah. Next time maybe avoid these synthetic agents because "mistakes" are harder to recover from and you can reuse the soil. Hope this helps brother ! 🚀
