@Ninjabuds, thank you so much I think it was too much water and the light too close to them because I bought a new light 250w, thanks for the response!

There could be a few things going on with your cannabis plant. Nutrient deficiencies, especially with things like nitrogen, magnesium, or potassium, can cause yellowing on the leaf tips. Over-fertilizing can also cause a similar reaction, so that's something to look into. If you're using well water, there might be chlorine or fluoride in it that could be harming your plant. And finally, pests like spider mites can cause yellowing, so take a close look to see if you find any tiny bugs on the undersides of the leaves.

Hey there don't worry . It's not really that much damage at all. I think what you are seeing is either underwatering. Or you pushed the nutrients slightly to hard. I suggest watering with water next time and then after that maybe feed at 75% the nutrients you did last time Again what you are seeing is just baby leaves being stressed out your plant actually looks quite well
