What problem u have?

Your leaf plant talk : wrong PH. It’s so high!. PH for hydroponics is 5,5 - 5,8 for a best results.

At first glance I don't see anything too wrong with your leaves, your plant is looking great in the photos. Maybe there is something that is not fully showing in the photos vs real life. Once I zoomed in on the photo I did see There is some markings on the leaves that resemble mosaic virus but I don't know enough about that to confirm or deny that for your plant. I would look into reading about it to see if that could be it. One other thing to note in your Grow if your PH. Normally in Hydro the PH to aim for in Veg is aorund 5.8-5.9 and this trends upwards when entering flower to aorund 6.2-6.3. Given yours sitting at 6.6 right now may want to try and lower that over the next day or so before any long term problems set in.

PH is to high. You should be at 5.8 for veg and bring it up to 6.2 for flower. Hydro PH range is 5.5-6.5.

I can't see anything REALLY wrong, no plant will ever have 100% perfect leaves, 100% of the time. Try and keep the leaves dry though. Since you say yout TDS levels are correct, I doubt it is a nutrition problem, in fact nutrition problems of any sort will not cause what you are seeing.

Yeah.. I'm thinking you need to start some NPK nutes as this might be the start of either a calcium or potassium deficiency.. I highly doubt it's caused by any insects nor do I think this has anything to do with genetics... and since you're not giving them nutes, that is where I would suggest you start. Good luck!
