Small Yellow spot at the edge of bottom fan leaf

Gongonstarted grow question 5y ago

Hi there, I spotted small yellow dots at the edge of bottom fan leaf. Plant looks healthy but this dots makes me worrie, it might be begin of something bad, so far its really small. Does my plant need more N? Or maybe it's because of LED COB light and needs cal mag?

I think they are water burns on the leaves when you water. Under the light, the drops of water act as a solar mirror. Always water when you are about to turn off the lights.

Looks like ur medium is staying a little moist. If the tip of the leaf is up against touching, or even in the soil. It will cause marking like that. But I will say tht isn't the only cause.... but ur most likely.

Sugar Leaves Turning Yellow Sugar leaves around top colas have started to turn yellow? No yellowing on any fan leaves. Plants are same distance to light and the environment has stayed constant. Only changed feeding cycle from alternating feeding/watering to feeding,feeding,watering (ppm still the same).

Help! Yellow fan leaves mostly at the base!Help! My girls have shown some signs of cal mag deficiency and I’ve added it at 1ml/l per plant for about a week now.. But it’s not improving or is there something else? Tight for space and wondering if this is also due to not receiving enough light? New growth looks ok?

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack Auto Only "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them. Thoughts?
