Leaves having/splitting like cuts issues

Hi , i have this symptoms appearing in some of the leaves. The plant appears to be overall healthy though . What could cause something like that ? Could it be due to low humidity ?

What is your humidity and temperature?

Temperature is around 25 - 27 C and humidity 20-30 % . 200Watt Cfl lamps 20 cm above

In general your humidity is low, but I don't think it's causing you the issue at hand. Sometimes pests, other than what we correlate with cannabis, can cause these types of signs. Roaches are good at helping themselves to a snack from time to time. If your grow is, on average, doing well, I wouldn't sweat it. Just keep an eye on things and see if you continue to have issues.

Actually checked again , humidity was lower than 20% ...

Get yourself a humidifier OR put a bucket of water in your grow space with a towel placed over the edge of the bucket...the towel will wick the water out of the bucket and allow it to evaporate into your ambient air, thus raising your humidity.

@Mathpkr So any update on this? I'm curious as to what you have found.
