Can someone tell me why some of the leafs look like this? I think it was because the light was too low but I am not sure

I’m it looks like the start of a pH issue. Make sure your meter is calibrated correctly and check anything that you put in the medium.

I didnt check it yet. My medium has a normal ph of 7,1 and I water it with tap water wich I leave 24h alone before I give it to the plants. So if its the ph value it should be to high right?

I would shoot for 6.5 for a pH.

What are you using for a medium? Depending on what you are using for a medium will set your pH value. Soil you what a pH of about 6.5 and coco or hydro you want about 5.8-6.2.

Thanks to some advice from Shaggygrower i got a ph meter… Costa del Sol filtered tap water that i have been using tested 7.3.

Followed my local grow shop advice and two drops of BAC ph-, and now 6.2. After just one feeding i can see a depth of colour that is new.

I thought i was having a rust mold problem. Turns out to be a ph problem. I underestimated the importance of ph.

I am using soil with a 7,1

Gotta drop it, its too high for the plant to take up the nutrients it needs.
