light/heat stress due to lights being too close. Diary says temp at 79 during the day.....but what is the temp under the light near the top of your plants, im betting its higher than 79. My advice is raise the lights 6 inches, and try to get temps down to around 73. Happy growing.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Wet shiny spots on leaves.I find occasionally such wet shiny spots on leaves. Any idea what the root cause and how to fix it?
They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶
I can rub them off with the thumb with no sign

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Catching a fade?Is this fade normal for a Crème de la Chem? Or is this some other kind of deficiency. This plant has not had any issues. She’s the most healthy of all of them. In the pics I’m trying to illustrate the purple color showing up on some leaves.

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?
