Questions Is this what a calcium deficiency looks like?
I'm seeing these little rusty spots forming on some leaves. I read an article here about calcium deficiency symptoms and wonder if that's what I'm seeing:
It looks like something is up but it is in the early stages and can be caused by many factors. To properly diagnose this we need to know a few things:
What strain is this
how old is it
Is this in soil or coco
are you feeding it and if so how much
what is the input ph
what is the input EC
what are your current temps and humidity
And any other things you might think important……..
Too much or too little of one thing can throw the grow out of balance and that looks like what you’ve got.

When did your problems begin? Phosphorus will act to lock out calcium and magnesium if the phosphorus level is too high. It can also cause leaf curl and thinning of the fan leaf fingers. Your problem is in the early stages but here’s a guide on phosphorus:

UPDATE - Plant Observations today:
The problem did appear to have slightly worsened. Her newest fan leaves since I defolled have grown quite thin fingers on them you can see the difference on the healthy ones. A fair few of those yellow veins have started to show up around various different leaves, and there's a bit of downward tip curl on the ones most effected. The rust spots though don't look to be worsening or disappearing, there's still plenty of healthy green leaves too so hopefully the flush will help.
25l of PH water went through her today at 6.9 This was more effort than I thought it would be lol she's heavy as but I got it done pretty effectively in my lounge room using a few things I found laying around the house I came up with a pretty decent rig to flush and collect my run off with, and was pretty proud how well it worked out. I tested EC, PPMs and PH of my run off and it was pretty through the roof 😳
Using plastic 90L storage tub with an upside down Milk crate wedged into it 💯🤣 I felt super innovative lol
PPM = 2330 (@500)
EC = 4.7
PH = 6.6
Are these measurements an uh-oh? Im unsure of what a healthy PPM reading should be or what healthy EC reading should be.. A guide of sorts would be super 👍
