Give us the grow details. Lights, temps, RH, grow medium, nutrients, grow space, etc. The more details the better. Can you zoom out on the plant with a pic?
It looks like PH fluctuation that happened a few days ago. When was the last feed or watering? Just my .02 based on the new growth with crumpled looking leaves with the yellow splotches, and it looks like it creeped out a little bit onto the fan leaves at the top of the plant.

Hi thanks for the reply. I have all 3 flowers on 150w 50-60cm space inbetween. Temp is a steady 25 celsius with humidty 45-60 approx. All done in a 80x80cm growtent. I did root booster and after 16 days from planting in soil I did the grow boost from bac. (4 days ago) I did half the recommended measure bc these are autos. I dont measure ph. The other 2 plants which I have on the same program are doing great.
The guy in the shop said I should invest in it later in my following grows and focus more on the basics in my first grow.. given your reply I shouldnt have listened to him haha… its just weird as the other two plants are doing great under same conditions thats why I said ill ask you guys

It doesn't take much for the PH to be off enough to affect the plant. Some soil will naturally buffer the PH but the Bio Bizz Light mix doesn't do that.
There are a few good brands of PH pens to suggest. Some users on the forum only use PH test strips and swear by them. Aspera, Hannah, and Bluelab are three brands that get a lot of attention. I use Bluelab equipment. One thing to consider is 1 point on the PH scale = 100. That means there is a big difference in 5.9 and 6.0. I'd recommend using an EC pen as well. EC is valuable information to determine how much 'stuff' is in your watering solution and how much feed you are actually giving to your plants. PPM is another way to measure the same thing. I used EC first and have stuck with it.

If the problem doesn't clear up you might flush the pot with plain Ph'd water at 3 times the volume of the pot. That is a quick way to reset everything at the roots.
