Does what you are feeding contain mg? That looks like a magnesium deficiency to me

Looks like it to me too.

Also, I see you’re growing in coco? Then you need to pay special attention to Mg and Cal intake. Coco partially absorbs these substances, thus depriving the plant of their availability.

Welcome

Welcome, I agree that CalMag is missing; especially with coco coir, attention should be paid to this.

Light cycle of 24h?

so your plants never get some rest. You should check your DLI, you’re likely giving too much.

but yes, this looks like CalMag deficiency.

The 24 hour light schedule stood out to me to. Unless it’s an auto then I can understand.

Give that baby some cal mag and about 6 hours of sleep every night and she will take off

Exactly! Our babies deserve some rest, including autos!

24/0 is often practiced with Autos, but it leads to stress and makes them more susceptible to diseases. In my opinion, 20/4 is the maximum you should subject them to.

It looks specifically like a mag deficiency, some epsom salts would be a better fix than cal-mag. Calcium is definitely needed in coco but too much will mess with the uptake of magnesium which can make this problem worse or could be a cause of it to begin with
