Oddly, it could be over watering, or pH. Those are the two issues that I know of that can cause this

Look at this leaf, it is a little curled and has burnt edges. First check if it is overwatered. Insert your finger 5cm into the soil to see if it is too dry or moist. At the same time, measure the pH value, which is around 5.5-6.5.

I water 2litres of water every 2 days at ph level 6.8-7.1 is this ok?

For my set-up, yes. That would be too often, or too much. The pH seems a little high as well. The 6.8 should be the upper end of where you are. I'm a hydro guy, so if you are soil, this all may be different. I've actually never grown in soil

Are you growing in soil? PH of your water won't really effect the PH of your soil and you need a soil specific PH tester or have to do a slurry test to read proper soil PH.

I personally don't test soil PH, a good quality soil will buffer. Not looking at debating PH, just saying what I do personally.

I posted this video in another thread today, pretty much explains how to change soil PH.
I love Mr Grow It videos, very informative!

You don’t say what you’re feeding or how often, or what media you’re growing in, but it could be a bit of nute burn. I agree that the amount you’re watering seems excessive, unless it’s really hot.
