Help with slight nute burn

Hello I've noticed the tips of my leaves are a little bit yellow & it seems to continue as the new leaves are shooting out. Though miniscule compared to some other examples I've come across what would be the best way to knock this on the head. I will say I believe I overfed when they were a bit smaller & have adjusted my ppm but the issue is still present. Is this a major issue or something that can be managed as is. The plants overall seem to be thriving but just thought I'd throw the question out there as to how I can deal with it though it could be just the after effects of my early mistake also. I've had similar issues in previous grows but not this early on. Any help much appreciated.

ppm: 260 (Noticed ppm dropping over last couple of days so upped it slightly)
ph: 6.0 (pH stable gradually rising over the week)
Water Temp: 19/20c (Chiller so no issues here)
Vipaspectra R900
AN 3 part pH-Tarantula-B-52-Cal/Mag only used atm
Everything else seems good.

Once leaves get damaged for whatever reason, they will always look like that. Just keep an eye on the new growth to see if you solved the issue, good luck!

Thank you...Well aware the damage can't be altered but I guess the best thing to do is wait & see what comes of it.
