FastBuds Galeto Auto - New training try

Okay, so after my plants began to show some bad signs at day 14 I raised a new grow question, and from the answers I learned that my light properly was too close to my plants, I immediately raised the light to about 25 cm. I don't think the issue is over feeding as I haven't given my plants any nutrients, except from maybe 10cl of water containing the smallest dose recommended of CalMag. But again it could also be the soil I use, but never seen this before using the same soil. I have also thought that maybe I over watered them, that is also kind of food for the plant. Anyway the grow must go on :) And.... A BIG THANK YOU to all the help I've got so far! Today I replanted my babies to a big 20L pot, and the roots where almost filling up the container, so maybe that also contributed to the bad signs? Anyhow, they seem pretty fine now and I do not see any new yellow spots, and I think they getting more green and healthy again. I also decided to start with the BioTabs nutrients schedule, as I also think they where getting a little hungry. The soil I use says the nutrients only apply the first 1-2 weeks, another reason to think they was not over feed, and maybe under feed? I used 2 BioTabs, 50g Strartrex, and 5g Mycotrex in the soil, for each plant. The other nutrients mentioned are used this one time for this week, and the only tap water On another note, after the recommendation in the answer to my grow question, I decided to only do Topping, LST, and Defoliation, but I still wait a couple of days before topping them Day 18: My plants seems to have fully recovered, and today I decided it was time to top them as it might soon be too late. They actually seems like they should have been topped yesterday, but I didn't have the time there
