Hello, did you drop water on the leafes ? Cause if you drop they will start to turn yellow and die.

Yellow leafs purple stem (not genetics)Three of the older leafs are turning yellow with purple/brown stains in them, also their stems turned purple with no other stems being purple in the plant. Is this phosphorus deficiency or nitrogen deficiency? Already top dressed with worm castings and bat guano high on P and k.

bottom leaves yellow Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? Th Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Overfeeding?Is this the first sign of nutrients burn? Some tips of the leaves are turning yellowish and two leaves are starting to make dark dots...maybe too much nitrogen? 🤔The temperatures in my grow box are a little bit low, but I don't think it's the case. The ph is regular.

Yellow spots on leaves Am I correct in assuming that the spots on leaves were probably caused by ph fluctuation? If so, is there anything I can do besides flushing with proper ph water?
