Que diagnóstico haceis de este problema. El problema está en las hojas guias (mayores y más viejas)???

HI, it seems you've been using a bit too much veg nutes no? They are curling down like a claw. I would give them just water for a few days.

I'm not sure what caused this BUT if the discoloration is only on old leaves and the new leaves are fine, I don't think you have anything to worry about (other than the police!). If this were my plant, I'd trim those leaves off and go from there. Good luck!

Did you just prayed them after it looked like that or was that rain from outside? if so, you might have burned some leafs a bit when putting them under your lights to soon while your leafs where stil wet. Also like TommyBVRSA75 said: changing climates like inside to outside or reversed will cause some problems. You should had let them getting used to lamps slowely for example by putting them higher above you plants, might even at the top of your tent for a couple of days. But overal your leafs have a nice color of green and i think you will be good :) Good luck growing

In my humble analysis, something is related to the changes in environment and lights. From outdoor to indoor (a police neighbor who moved into my apartment block made it necessary to change the nature of the grow, and this happened to me when: 1- I switched to indoor with LED (full spectrum) 2- when I had pests and used soap spray and nettle tea with foliar application 3- when I changed the cycle from 18/6 to 12/12. I see it in the most recent leaves that have grown since the changes I've mentioned; they are perfect as you can see in photo 3. But the older guide leaves have developed these yellow spots. I don't see any over-fertilization or deficiency, and what I've noticed is that these affected leaves are falling off, but the new ones are beautiful and very healthy. I don't see the problem spreading.
