Upward curling of leaves
FullFuzzystarted grow question 6y ago
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Hello.. Hope you are well.. Tbh shes very young still and its probably damage from water wen she was a baby.. Her leaf curl is just drying out at her tip because of prior damage.. Ideally u shud b watering her with ph'd solution at ranges from 6-6.5 in soil.. Because she's at wk 4 i dont think she will of consumed all potential food in soil stil so if u do decide to feed her only give her 1 feed at a very low ratio.. Stay safe n gud luck.. 👍🍀

My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)Leaves. Color - Yellow

Yellow marks in leaf center and weird King Kush?There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?4y ago
