Yellow tips

overfed if u've fed it

Hey, took a quick look at your grow log and I'm not sure but I think I see stuff starting on multiple plants. Tips on one is yellowing, other one is curling, could just be my eyes and the angles playing tricks. Either way, Let's have some fun: 1) Are you running organic amendments or using nutrients (bottled or powdered)? if organic skip to #4 2) what nutrients are you running and at what strength? 3) Are you watering every couple feeds, or feeding every time? 4) Are you adding cal-mag? 5) What light are you running? And if it is adjustable what power are you running it at? 6) What height is the light at above canopy? 7) How often are you watering, and is the soil drying out between waterings/feedings. Hopefully something there sticks out when you reply and we can try to get you back on track. Good luck.

There's a couple of other less likely possibilities. One is that your plant might be getting too much or too little water. Another is that the soil might be too acidic or alkaline. Finally, it could be a sign that your plant is getting too much light. If you've already checked for the more common problems, like nutrient deficiencies or pests, then you might want to take a closer look at those other things I just mentioned. Next time you water check the ph of the run off water if it's not in a good zone then flush soil with water ph 6.4

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.
