look like bigger plant is suffering from magnesium deficiency, and smaller plant is probably rootbound and suffering from nitrogen deficiency. https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.
I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!

Is this nute burn or other deficiency? I did increase the feeding a bit. But also just came out of a calcium deficiency. Not sure if the one with brown edges was from before tho, I forgot to clip a couple leaves with brown spots

Burnt looking seedling
What's going on with my #2 seedling? I thought it could be light burn and raised my light by 4" but the odd coloration on the tips has gotten worse 18hr later. It also doesn't seem to be drinking whats in the coco yet so I'm cautious about feeding.

Some leaves are burnt but the ph is good, watering is good light and temp good soil seems good and balanced. The humidity is very low can it be because of humidity?
