Hasn't spread too bad but started about a week ago when i added the calmag
Am i on the right track?

Let's go with maybe. Looks to be a cal/mag issue, but is it because you've been under doing it? Or is it due to a lockout for some reason? I see your feed pH, and your soil mix, but not the current pH of your soil.
If your pH is in range, and you've been giving a source of cal/mag, time to see if something else is interfering... P&K can cause calcium uptake issues...

Start with a soil slurry test, equal part soil and water, let set for 5 to 10 minutes and ph & ppm.

This will give us a more accurate idea of what's going on.

I'll add cal/mg tends to be much more needed under LED. So if that was your first cal/mag feed... I'm leaning your on the right track.

 

[CBgrower]

Ive fed twice with cal mag. Ill do a slurry test when i get home in a day.
Im gairly new to LED used to hps.
This presented the same way on my fugue state. I started feeding it megacrop when it did and slowed it down but didnt stop. It doesn't seem to have hurt the yeild but morebof an eye sore.

- hard to say what that is just yet, symptoms not very definitive yet,... Ca defc. can start out looking like that though, and as Arthur said, LED is a known factor in apparent need for elevated Ca levels,...
So, you water is starting at about 225ppm after blending? that's still pretty hard, I'd run it at 150, especially with Ca-Mg going in,... hard water does have CaCO3 in it, and that's part of the potential problem, but as far as available Ca++ goes, it may not be a good source.. meantime cumulative build-up of mineral load in there can cause pH and uptake issues, but I don't think you're there yet....
yes as always, pH is the first thing to check out! Look into a good pH probe, like the Accurate 8 (or identical unit under a different brand name), or chip out the extra $ for a Blue Lab pro' unit.... this will tell you if there's a possible lock-out issue, in which case adding more nutes may make matters worse, not better,...
When to test the slurry, check the ppm's too,...
How far away is the light? Distance is a big factor in exacerbating such apparent defc.'s....

Fugue State- :drool:..loved mine! .... the yellowing on her looks more P defc. related,...

 

[Arthur]

Interesting your pheno leans heavily towards the Toof decay. I've got 1 at 52 days that is very much more of the ghost train haze structure... actually very hazy... 50 inches now...

How's the girl?

I was wondering if im overloading on ca as well. Should i switch to straight RO and add in cal mag? The girls are doing ok there is more deficiency showing but it seems to be in check. My sour crack shows a few spots but not many on old fans. I see some mag deficiency that i havent seen in previous grows. I saw that too much ca will lock it out so im leaning that way.
I will feed the girls 2ģ gallon of MC starting now as i dont want them runnin out of food.
I pollinated all my lowers on the ghost toof and the sour crack with previous reversed sour crack pollen yesterday.
Edit sorry W the lights are at 24 inches give or take a few. I was running closer up to 18 but read about causing deficiency symptoms.

SOUR GHOST?

Will be doing the same with a gold glue currently running.

I run straight RO, drop the tap, it will ease your mind to KNOW what is going in.
I live in a delta area, and the water quality changes twice a year. Half the year I could get away with the tap, half the year I can't. Better to just not worry.

Yes the ppm here can go up to 800 plus in the winter. Ill start straight ro and just support it with cal mag. I have Greenleafs cal mag pro any idea what dose i should be adding with the ro? Again im new to led and im not used to adding in cal mag.

 

[Arthur]

I just start with the cal/mg, get it mixed well and off I go. There are re-mineralizer available, I haven gone that far yet. But am looking, time to get the house off this crap.

Seems they always find issues (Flynt Mi) and don't tell anyone.
