Hi!
It looks almost exactly the same as my auto ghost cookies, except mine is way way worse atm. It took me a while to MAYBE figure out what's wrong with it and in your case I think it is the same
Light burn from too intense lights. You can see that you have the yellowing in the middle where I suppose your led light is and the leafs are starting to turn yellow and show calcium deficiency 'cos calcium is important to process light and the leafs can't just process it all anymore.
You have couple options. Either move the light to different position to give the middle part some rest, or you can add CO2 to 1500ppm to help the plant photosynthesize more and this way it can use more light, or you can try to add more nutrients so she can grow in that environment possibly. Either way she i stressed so you should raise the light and give her couple days rest before going full blast again

Looks hungry mate, despite all the feed you seem to have given. Yellowing means the plants sucking food out of the leaves, spots like that usually indicate deficiency, if it was burn it would be the tips. LED is infamous for sucking the mag out of plants, so could be that. Is the issue starting at top, bottom or sporadic?

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?

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips. To tackle this, I used yellow sticky traps and watered with nematodes. I also sprayed BAC Plant Vitality Plus on the leaves.

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

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?

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.

Tiny holes!?This morning while looking I noticed tiny little holes on some of the leaves on one of my plants. I didn't see any pests with my eye, and I tried to use my phone the best I could but couldn't see any. I've also heard this could be environmental/viral. Any thoughts or ideas?
