Looks like calcium deficiency. Spots, and twisty points of leaves.
Also some stress on leaf stems.
Are you using hard water?
I used to get similar, from using phosphoric acid, ph down, which reacted with calcium in water, and the extra cal/mag used to treat the apparent deficiency. This creates calcium phosphate, which isnt very soluable. Look for white crust, at the soil line, on your pots.
I'd first look at ph at the rootzone.
Lockout looks quite similar, as calcium is one of the first to show.

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?

Super thin leafs at the TopThe leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?

First grow with autos, are these growing too slowly after a week?It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

Normal trichomes or something bad?Dumb question, I started noticing this on my leaves. I recently battled with insane humidity which I was just recently able to fix, and was wondering if this is normal/my usual over worrying or if it's some sort of mold/mildew/fungus or something I should actually worry about.

1 out of 3 doesnt do as well as the othersIm just wondering why one out of 3 plants, does not perfectly well while the others seem doing awesome. Can it really differ from a strain that it shows signs of light stress or nutrient burn while other plants seem to do well with it?
I added 3 pics, 1st one showing the meh one

Identify Issue: Brown Spots, Lower leaves first, from outer-tipsShowing up on 2 out of the 5 in my soil bed. Front 2. Transplanted 10 days ago, went well enough.
Watering with tap water, never tested but didn't have an issue last run. Same soil, but I did add 8 cu ft of new soil to the top. Gently amended with b6, Kashiblend, coconut powder.

New growth looking strange and growth slowed down (wilting?)The new growth of my plants are looking a bit strange, and growth seems to be slowed down.
Could this be that the light is too strong? Or can this happen if the humidity is too low?
I already installed an humidifier but looks like its not helping.
Whats going on?

Brown/white spotHi everyone. The plant is a photo on her 7th week of veg. I give solid ferti and diluted compost tea water then appeared white spot on old leaves and the new leaves have tips burnt.

Spotted LeavesMy ladies looked good until recently, it has been very warm the last few days. Then they began to let their leaves hang down (didn't get enough water) and gradually turned yellow, now they are getting spots. This is my first grow and I am not sure what it could be.
