Bubble Gum Auto Issue

[Super Weeder]

Hi first time grower/poster long time reader and needed some assistance with a recent concern I had with one of my plants. This particular plant has had Cal deficiency issues on/off for the past month Treated with Cal/Mag and it seemded to fix the issue. Now in the past day at the top of the plant a few of the bud leaves have some rusty looking spots. I read a bunch of different articles about rusty leaves and a lot of different conclusions were made. Some said leaf burn, some pointed the problem on Nute lockout while others said it was a fungus issue. I really appreciate the help I am just so close to the end I wanted to get some advice/opinions on the possible problem. Also have 3 healthy plants in the tent and if this is some kind of fungus I wanted to get it away from the other plants.
My grow has been all organic and PH is always kept around 6.5, temp 65 night/75 day humidity around 38%.

I’m also a new grower but looks like maybe not enough phosphorus And a little bit of Chemical burn

Bonsai is correct. Plants like lots of phosphorus during bloom.

Welcome to 420,Super Weeder- Glad to have you with us!

You'll get a better diagnosis if you post pics in "regular" light-it's really hard to see the
whole problem in the blurple light....
It does sort of look like light burn-how far is she from the light?

 

[Super Weeder]

I appreciate the diagnosis and all replies back.. I think you are correct that this is light burn because only the two buds closest to the light have the issue. They are roughly 18” from the light while others are close to 24”. I also have been using liquid bone meal in my tea which is supposed to help on phosphate. I will see if I can pull these two further away from the light.
Please let me know what you think on these other pics..Thanks

I attached a few more pictures in white light.

This is third shot is from a healthy looking bud that is further from the light.

Hey dood

Some phosphorous deficiency, occurred further down on plant as it went into early bloom. Only happened to one as well.

 

[Super Weeder]

That looks just like what I have, I will increase liquid bone meal in my feedings in addition to moving over the buds.. Again I really appreciate the help hopefully no further damage I am assuming the leaves can just be trimmed off after harvest and the buds should still be good.

No problemos, happy to help.

It's okay to leave them on since phosphorous is a mobile nutrient and the plant can move it around to different areas for more growth.
