Yes. Give it a flush with pH'ed water.

Sometimes it can be difficult to measure the pH of plain water so adding a tiny amount of nute to get a reading is fine.

It's not really looking like a nute burn though so I'd just keep going and stick to a good feeding regime. Young plants in veg can show all sorts of leaf anomalies unrelated to what you are doing...don't panic.

A pH of 6 in coco in veg should be fine. You're likely overwatering them though so just be careful of that. Once a day just a small amount around the outside of the roots should be more than enough at this stage.

If your pots are heavy wait a bit before watering.

HELP!!!
My plants seem to be developing nutrient burn. They are yellowing around the edges and starting to cut upward. I think I overdid it on the last batch of nutrient water. Can I flush it with 5-6 ph water? Pictures and more details attached

I think you nailed it StickyNugsAZ in a bigger room an more open enviornment this would not of happened.

I didn't see that fan. Well spotted.

Yes 30⁰C temps in the canopy and higher in the top of the tent with that fan will wind burn the crap out of them which is what's happened.

Keep temps down now your in flower...23 to 24 even a bit lower with really big buds.

You do not want alot of strong direct air from that fan. A gentle indirect breeze below the led and above canopy would be better

I've never had that issue.

Read the leaf problem part of the website. Looks like stress of some sort.

Hi all. My first grow. The plant is over 6 weeks old. The upper leaves of one plant do not want to open and are twisted. Just in case, I raised the lamp to a height of 40 cm from the top of the cones (it was 15-20 cm), added another fan to lower the temperature lower (it was 30 degrees Celsius, now 26). But maybe it's something else and it's not overheating, as I suggested? I feed my plants with Advanced Nutrients, do doses according to the calculator on their website. A neighboring bush, with the same care, feels much better and does not have such problems. Where could I have made a mistake and how can I fix it?

Not sure of my plants are unhealthy or not. Larger one seems to be developing a brown spot on one leaf. The other two have rounded leaves and one seems to be growing differently from the other ones

The larger plant with the brown spot is critical Northern Lights and the other two are super skunk if that matters

Two leaves are like this. What could be the problem? The pot is in the open air

I was adding soil with a pot, and it spilled some on the leaf.. looked, there is no pests or insect

[Bluey]

You have pests on your leaves. I can see two types just in the first photo of the last lot you posted. Look closely and you will see them.
