I agree - looks like a little nute burn. Can you post a photo(s) of the whole plant?

Have you grown in this soil before? What is your nute feeding history??
I grow in OF + Light Warrior mix, and don't feed for the first 3 weeks, then phase in the nutes every other watering at 1/4 then 1/2 strength.

If you just repotted into more nutrient rich soil then there's no need to add anything IMO just yet.

The roots are spreading into your new soil and using what's there first.

However though it does look like you may have a Mg deficiency with the small brown spotting and pale coloured parts to those leaves.

Sometimes it can be caused by an overdose of Ca which will appear as an Mg deficiency.

Have you added any calcium to your mix? Dolomite lime etc?


If not then you could look for a calmag supplement to help.
