Day 51 ----- YOU CAN DO IT"

Still having issues... the rustyness is still there and slowly spreading around the tops of the girls...
Pictures taken of all the same plant...after cutting away all infected areas of the girls afew days ago and upping the calmag to 1.2 ml per ltr, also keeping humid just below 50% most of the time....most are like this but not all..its hard to say if its the ones under LED as i been moving them around to suit height situations...

Wondering how bads this is gonna get gonna post on 24 hr help as you guys have been telling me...deffo situation...thou they still look good! growing and budding well, just worried the rustyness will start affecting them..!

They are switching from big-bud to overdrive today. Missed sunny picts AGAIN will try get better RUSTY ones up tomra....

That's looking a lot like a Ca and K def to me, AutoRocks. It looks like your leaf edges may be turned up, almost like during heat stress? If so, it could be a salt build-up in your soil causing a lock-out.
Refresh my old brain, Brother. How much run-off do you get when you feed, and do you give plain pH'ed water between feedings at the same volume?

Sounds Good Red

previously Upped Calmag to 1.2 per Ltr...(Plant Magic)
Using Sensi A/B (Part A 3-0-0) (Part B 2-4-8) Mixed equal parts 2mls per Ltr feeds, Not much run off during feeding, they get about a 1ltre per 15Ltr Pot.
Only a few have turned leaves, But the ones that have gotten worse, Not pumping them with too much heat, interesting about the lockout scenario..hmmm! Thinking on what a mission would be to Flush Lol! they all massive! Also i don't give them Plain pH'ed water between feedlings!
Still gray and dull here, We in the middle of summer Typical Irish Weather Still Shite!

HH asked me also about how much i flushed inthe middle stage... Well 30 Litrs per Pot, On TaNgs says i should use 45 Ltrs.. Gonna up the Calmag Abit and flush aCouple to see any changes...

I had the same problem and upped my cal/mag to one tsp.or 5ml per gallon and moved my led's up a little.Also gave them a little nitrogen along with bloom nutes and they seem to be getting better

This is where you're gonna start developing your own style of growing, AutoRocks I've only been doing it for a few years, but I've never had to do a real "flush" on a plant. I always water and feed to 10-15% run off, and it seems to keep my soil fairly salt free. On the other hand, I live in the high desert, so that excess water in my pans gives me the humidity I lack. If my RH hits 40% it's noteworthy!
10X what Nammy said, don't be afraid to get aggressive with the cal/mag.

are those ones under the LED lights?

I would bump the Cal / Mag up to 2.0 ml per litre at least for the new few days to see if it stops the problem.

I think it's probably related to the LED lights and the fact that cause plants to need extra calcium. In order to verify we bump the Plant Magic - Magne-Cal+ up to 2.0 ml per litre and see does that change anything. If it works then we know next grow around to start using cal mag earlier and a bit stronger than this grow. Let's see.

I had this last grow and it spread across three different strains in different types of rust. I read a lot of cases where it was attributed to a deficiency but I believe it was Leaf Spot Fungus (LSF). Killed leaves but eventually stopped spreading.
