I have two problems,

1) Yellow Leaves, good or bad?

2) White spots on my leaves, good or bad?

Need some more details dude:
What are you growing in, what you feeding them?, how old are they?, what stage you in? etc.
Yellow leaves could mean a few things. The spots I am not sure about (mildew/mold?)

Outdoor plant, I give it water!

It is like two feet tall.

Many flowers, buds are almost coming!

What the hell i have the same problems. Both the yellow leaves and the white spots and i also am growing outdoors with a plant around 2 feet and just starting to bud

same here,except the occasional,normal lower leaves.what r the white dots?(outside)

can you rub off the spots? if so, maybe fungus or mildew?

My yellow leaves are towards the bottom.

I'll try to rub off the white shit, brb.

It could also be spider mites, check under the leaves for tiny little webbing. If so, you need to douse them with a dish soap, water, vinegar mix.

I am having the same problem only I am growing hydroponically. Its really weird. The spots start out kind of silvery white and then they turn yellow after a day or so and then turn brown. It has affected most of my plants and I have no clue what it could be. The spots are a couple centimeters big. If anyone has any ideas please let me know. Thanks!
