Lack, excess, or is it the water? I watered with top veg Green explosion and big one. The pH was from 6.1 to 6.3. I also let the water sit in the sun for a few days, but I don't know if that was enough. It's also really hot.

I can see the light green color that is developing in between the veins of your leaves. This is the first sign of magnesium deficiency. It looks like you are growing in coco? If so you should be adding a cal mag supplement every feeding. This will clear up your issue. Good luck!

In the cultivation in coco, the substrate is ts3. I have a 4" extractor running all day and also a fan inside to circulate the air.

Hi @sabalero420 variations in PH and excess heat seem to me. fertilizers tend to lower the pH of tap water a little, if you only give tap water or nutrients, you should always set the pH to 6, this is where these variations occur and the leaves burn. try to get an air extractor with more power and add another fan to make better air circulation through the grow. good luck mate 👍
