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

What is causing this?
What is causing this? It only seems to be on the older leaves and only on this plant. They’re all being fed the exact same.

Burned or finishing early?
So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!

Leaves dying
I removed these dying leaves, they were burned, with signs of necrosis and curling down. Now the plant siting next to the "sick" one started to show some early signs, similar to what her sister showed weeks ago 😪 Does anybody know what is going on?

Auto seedling discolouration
This discolouration has appeared on the leaves of one of my two gorilla glue autos, it has been there since the first true leaves which makes me think it could be genetic? I’d like to know if anyone has more information on the cause or if anything needs to be done about it.

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Wilting leaves and copper spots? Save Me!
These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?
