Is this nitrogen deficiency or something else?

CookiesAndCakestarted grow question 5y ago

Hello everyone! One of my plants has some fan leaves and new leaves yellowing at the bottom (and some are crispy). The plant is very bushy but from what I understand this could be nitrogen deficiency but wanted to check. The other plant is smaller and doesn't have yellow leaves

I checked your diary pics. No deficiencies. Natural dying of older leaves that dont receive much light.

Is this light burn?Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!

Let it grow or cut it out?One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...

Leaves turning yellow and dying I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

Help validating what this is My plant seems to have developed some kind of deficiency/excess. I researched and think that it's CalMag deficiency, added CalMag to my nutes (1ml/l). Just wanted to check in with the experts here to get a second opinion. The growth seems slow I'm afraid I may have stunted her 🤦
