Spotty/Blotchy Discoloration on leaf.
What is this spotty/blotchy discoloration on this leaf? None of the other plants have it, it didn't brush off when rubbed. Hoping it isn't a mold or a pest...I have been keeping the humidity around 65% with good airflow, but I'm wondering if it's time to bring it down to 60%.

Spots on leafs, and lime green tops
I am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though

White/Yellow snipes on leaves? (13th day of growth from seed)
I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions. I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet

Can someone look at my newest pics? 1 of 4 plants (shortest of the 4, so its not light burn) has about 6-8 fan leaves like pics. Happened 36hrs after i did a big flush, that brought my ph down around 6.7. I think its either too much nutes, or lacking phosphorus. Help!

Do my girls look healthy? There's small lighter green patches here and there and some leaf curl. I might be a over analyzing/reacting. I'm a little paranoid but autos supposed to be finicky and stunt easily, and can go from bad to worse very quickly, from everything I've read.Thx

Hello GD friends. My little Diesel Automatic is showing some odd mosaic'esque coloring on the baby leaves. I'm inclined to just let it go for now and see what happens. But if there are any suggestions on helping her out, please let me know! Thanks!

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!
