You have way too much nitrogen. The issue looks potassium deficiency, with calcium deficiency. Vegging npk ratio is 3-1-2, flowering npk ratio is 1-2-3. Good luck and happy growing 🌱 remember to select a answer as well. 👍

Excess N looks like to me - that will lock out calcium uptake..

Cal deficiency?Is this a problem or nah? Brown spots on leaves, mostly on the one plant that is farthest behind on flowering. Thought it was calcium deficiency also contributing to slow flowering so I hit the plant with some nutrients a few days ago. Concern or just end of life stuff? Thanks!

Quick glance Make this an easy one, I'm aware that too high nitrogen levels will turn the plant a deep green color. Just wondering if any ol'heads can notice from a glance if the color is off. And any suggestions in general from a glance at set up and diary. Please thanks

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?

One plant is looking bad but still doing it good leafs hanging it looks strange If you can see on the picture one plant is looking a little bad. She grows in the length better than the other one but the colors looks a little like yellow or lightgreen and the leaves hanging down and feels hard or raw. But she's still doing it good! Over feeded? To much water?

So- largest plant (photos above) yellowing lower fan leaves, overall light green colour on the entire plant. Possible Nitrogen deficiency? Otherwise she is healthy, budding up well and looks great. Any thoughts from the GD community? Thx as always!

Anyone experienced leaf burn from a high intensity LED? I think that's what has happened to a few of the plants and I hope I caught it in time but the yellowing leaves don't seem to be getting any greener. They are starting to get a few random rust/dark spots on affected leaves
