Early in my indoor gardening career my plants got sick.
It first affected one plant then quickly spread, plant-to-plant.
The leaves got all wrinkled, it was hard to root clones, growth was slow and yield was low.
I checked every marijuana specific grow guide and talked to friends; no one knew what it was.
Then I read in an Ask Ed column about someone who had the same problem and it's prevention/solution.
I had tobacco ring-spot virus.
It's a virus that only affect tobacco--and marjiuana.
If a tobacco plant gets it, the virus can survive the drying/curing/manufacturing process (hardy things those virii).
I roll my own cigs. When I handled the infected tobacco I got the virus on my hands and when I touched the pot plants they got it.
I tore out all those plants, cleaned-up the growroom real good and re-started.
Another time I got a few clones from someone and introduced them into my growspace. I didn't notice the donated plants had spider mites. In a few weeks I was overrun. Spider mites don't travel far and the donated clones were a ways from the other plants. Undoubtedly they traveled on my hands/clothes from the infested clones to the rest of my plants.
So clean up real good before tending your plants. Change clothes (I have a pair of overalls I wear ONLY while tending my garden. It hangs on a hook right outside the growroom door0 and wash up real good (water only works-- you don't need antibacterial soap or soap at all).
P.S. Like I mentioned, virii are tough. If you've got it on your hands and touch a doorknob, the next person to touch that doorknob will get it on their hands.
