Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!
My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.

Nutrient deficiency?
What type of deficiency is this? I think is from lack of nutrients in the soil. This auto been in the 3 gallon pot mixed with Gia green 4-4-4 for a month with just watered. I fed her ff tiger bloom 1 day ago to get her some food. What should I do?

Purple stems on some seedlings?
Why would the plants on that edge of the tray have purple stems? Nutrient deficiency? I noticed the one I checked with a purple stem had more roots showing from the rockwool cube than any others... think they're trying harder to get to the juice cause they got shorted?

Why is one leaf yellow AND shiny?
Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?
