looks like a very slight nute burn. Use straight PH'd water for the next few watering s.
If it persist, flush them good !

I agree it looks like the tiniest bit of nute burn, but I would handle it differently.
This is right where I like to keep my plants. I up the nutes until I see that little bit of burn and then I know I've reached the max nutes. You can back the nutes of just a bit, but I think switching to 100% water is a bit of an over reaction.
uhm, i've actually been doing just distilled water, no nutrients.

Then flush the plant if you havn't yet. Salts / Nutes build up in the soil.
Even if your on straight water doesn't mean they are not there.
Are you using soil with slow release fertilizer?

okay, thanks for the info.
so is there a way to back off the nutrients or should i flush the plant?
i'm not sure if my soil has slow release fertilizers in it, i just looked at the bag of the soil i used and it's just called all-purpose potting soil, and it says it is free of any chemical additives.
