¿Ataque o deficiencia?

You need to get some insecticide pronto.... I'm seeing markings on your leaves from several different insects... for the small white spots, I would recommend Dr. Zymes Eliminator (pick it up on Amazon) or some Spinosad (from any garden center)... use as directed spraying just before lights out... At the very least (and I don't use this as I don't think it's terribly effective against a whole host of insects but...) you could try some neem oil. The problem with neem oil, other than being not-too-effective imho, is that you can't use it when your plants are in flower.... the two products I've recommended are both organic and can be used against a wide range of insects (spidermites, aphids, thrips, whiteflies) all the way through to harvest... and they will kill all stages of the insects - adults, larvae and eggs.... The long white trails are leaf miners and these are a little more difficult to control because they actually live inside the leaf... Grow Diaries doesn't like us giving out a link to a website (thanks to some really horrible spammers) so I'm simply going to quote from one of them for you: "Keep your plants in tip-top condition. This is good advice any time, but if your plants are healthy and thriving, they can better withstand the leaf miner damage. Plants that are barely hanging on are more likely to die if they lose a lot of leaves. "Make sure your plants have enough water, as drought stress can really weaken a plant. By the same token, fertilize the plants as recommended to keep them well fed. Healthy plants can withstand more damage and bounce back faster than stressed plants. Monitor Your Plants "Check your plants at least weekly. Leaf miners often attack the first true leaves of a plant. Check the bottom of all the plant leaves for eggs, and crush any that you find. If you find leaf miner tunnels on your leaves, squash the larva at the end of the tunnel. You can remove the infected leaves from the plant if the plant has enough other leaves to manage. Do not remove more than 1/3rd of the leaves on any one plant." Good luck!
