Hi Roberto.

What Rwise said is a little bit of a tongue-in-cheek way of saying “we need more info to be able to help you.”
We can only help if we know:
pH
temp/humidity
light info
grow medium

The more info you can share, the better we can help you 😉

I keep ph at 6.4 temp 25-26 while lights on and lights off at 19-20 i have hps lights at 400watt and i grow them in coco mixed with clay stones

Plus ive got this sign aswell

1) be sure to let your pH vary up and down in the recommended range. You don’t want it to always be 6.5.
2) what is the humidity? It plays a key role in plant health
3) is it possible you have a fan blowing directly on the plants?

 

[Roberto4536]

It doesnt go up and down i dont use ph at all i just check it goes 6.4 everytime by the nutrients
humidity stays around 47%-50%
and yes they are fans blowing but not to the same spot all the time it moves left and right and its from a distance

That type of curling is usually caused by one of a few things:
(heat
Wind
bugs)
Just to name a few.

As i mentioned before, the pH fluctuation is critical to allowing the plant to take up different nutrients. See the chart below for reference. Then refer to online guides for cannabis deficiency symptoms. You might be having a boron deficiency since 6.5 is way outside the range for boron uptake.

So i should use ph down sometimes?

Could you take pics without your HPS on ? Too much yellow to properly see what's wrong with your plants.

 

[YYCannabis]

Yes.
You should monitor your pH when you mix nutes.
