Spots on leaves

started grow question 6y ago
Could this be the beginning of a Phosphorus deficiency? Or something else? It’s not really found on my oldest branches, but more my newer ones.

I would say that's a slight calcium defeciency, just add some cal mag to the feed.

Are these pre-flowers?
My plant is still on an 18:6 schedule. This is my first plant. I noticed that these were growing more rapidly after topping. Are these pre-flowers. I don’t know if it’s an auto flower seed. Here’s a pic of what I’m talking about. Should I be preparing for flower stage?

Scharze und braune Flecken auf den Blättern
Es ist die Watermelon Auto. Ich habe heute einen Bud mit Schimmel entdeckt und entfernt. Ist das ein Pilz in den Blättern oder nur Calicium- / Kalium-Mangel? Es sind zum Glück nur wenige Blätter betroffen.

One leaf issue?
The only leaf in the entire tent looking a little mad. My instinct says leave it and see if any others pop up. Thoughts?

Is she worth it?
What happened to this seedling? It sprouted with 2 cotyledons (looks like a piece is missing from one) but only one true leaf. It also sprouted with the leaves facing straight up but now they are all facing to the side. Is it worth keeping? It is on day 5 since soil germination.

Twisting leaves?
The leaves on Blueberry #1 (top right) are starting to twist a bit. Should I be worried? The only changes I've made recently are: 1) increasing light up to full wattage and 2) adding second fan (lower left) to add more air circulation.

Leaves are not developing much ?
The stem of my seedlings is growing well, but the leaves are not developing much. Is that bad ? When growing indoors I think you just need to put the lamp lower, but since I am growing outdoors, so with sunlight, how can I fix this?

Should I reduce N further?
Hey everyone, it’s been 11 days now since I noticed a Nitrogen toxicity, and I adjusted feed to 650ppm and notes in ratios according to GHE feedchart (numbers in diary). Just wanted to ask if you all thought they still look like they need less Nitrogen? I could reduce calmag?
