Day 54: The plants are growing fine, and looks healthy. It is maybe going a little slow now, but I think that's normal in the current state. I have also decided to feed the girls a bit, and from my many recommendations gathered from my grow questions (And a big thank you to all the help!), auto-flower don't eat as much as photos, so I gave the half dose of the nutrient schedule recommendations (Approx 1600 ppm). It is given to them this one time only, for each plant, and afterwards i am back to just plain water (240 ppm)
Hey, your little ones are not looking to bad at all.
I would not worry to much about it.
One thing of advice is that autoflowers are not as heavy feeders as Photoperiods.
If you give them to much feed they can sometimes enter flowering early.
They will benefit from a flush entering flower to clear out any built up salts in the soil before feeding gets heavy.
this link is a good reference points for strengths of feed. still have to go by what your plant is telling you though.

Best of Luck and Happy Growing!
My plants are becoming more yellow and now also showing some brown/yellow marks. I'm afraid it’s because I may have splashed some water containing a little bit of CalMag on them one time, not knowing better. Might that be the issue here? And most importantly, what should I do?
It does look like they have had a bit of burn from some water droplets.
are you balancing out the waters ph as well? or just adding in calmg to its water?
Your diary says the lamps distance to the plants is 10cm, or just under 4 inches.
That is way to close. If it's meant to be 10 inches that's also a little close for seedlings sometimes.
I would aim for anywhere between 25-35" for sprouts on a 600w led if that the true wattage its pulling. Some of them also have dimmers.
Some of this could be light stress but I'd like to confirm the lighting distance before thinking about that.
If you light manufacture has a PPFD map you can reference then use it as a guide line and adjust from there.
Good Luck and Happy Growing!
Main lining involves LST so yes, you are actually using both principles, although LST on its own does not necessarily involve topping.
Also, 18/6 is better for your plants, they need sleep to function properly. Don't worry, growth will be identical, if not better with more sleep.
Ease up on the nutrients, they are very, very dark green, half to three quarters strength nutrients is usually plenty.
Do not defoliate, - less leaves = less energy being made = less growth.
Since they are autos and considering what you have already done to them, I would just leave them to do their thing without further interference.
Nice job though.
