Is that coir
Kinda looks like a sulphur deficiency however there’s a few other things it could be.

How far away is the light
Is it dimmed
How often are you watering
What is your ph ( if not a organic soil grow )
Are you following the bio bizz chart at full strength

What bio bizz nutes are you adding

Thanks for your answer, its coco soil from biobizz. My ph of water is 8 but i used biobizz ph down to get it to 6.5. The light is 50 cm away and is 100% bright. Im watering each 36 hours 1 liter. With the biobiz fertilizers about 60% of what is sheduled. But i didnt bought the calmeg from biobiz yet but everything else.

lights too close & power to high, move lite 30inches above & turn light power down to about 60/70%, only water when soil is pretty dry, i use coc0 coir & water about every 4 to 5 days in 3 gal cloth pots, thats my method

Your ph is to high for coir aka coco

6.2-6.5 is for soil
5.8-6 is better for coir

The bouncing around of the ph may well be the issue however agree with @HerbalEdu coir ussaly needs cali mg and it shouldn’t hurt

Oh and dim that light to 75/80% btw and raise it to 25”

None of us run leds at full power

while soil use to naturally buffer ph when growing in hydro and so coco controling feeding solution and run off pH is key. moslty to prevent any salt build up.

(you need to control and adjust the pH after mixing the nutrients and others additive as some of them have a tendency for lowering the pH.)
