Well, other than calcium and related phosphorus, it might be slight potassium issue.

Leaves still discoloring
I was thinking we had a def in calcium ( see last question) and started to just treat with 6.5 ph water, cal-Mag plus 2.5ml/g everyother day. Leaves are turning a shiny burnt orange color and drying out on the edges. What is going on and how to fix it?

Purple Stems
On Day 11 i recognized purple stems but only at the 2 top leaves, i hope it is only genetics or maybe the cold night 2 days ago when it went down to 17 celsius.

Phosphorus deficiency? PH problems?
I'm on day 56 of flowering, and only the Mimosa Evo's leaves are starting to turn red, pinkish purple. I suspect a phosphorus deficiency/absorption problem due to the pH being too low. Or is it genetic?

Gelbe Blätter, mit Lila Flecken
Meine Pflanze hatte Nährstoffbrand, dann hab ich erstmal keinen Dünger mehr gegeben. Jetzt bekommt die Pflanze gelbe Blätter mit leicht Lila flecken. Nährstoff mangel? Oder Blattverfärbung durch Blüte? Oder immer noch Überdüngung? Ich verwende BioBizz Starterpack.

Does color change primarily happen as a result of cooler temperatures at night and lack of nutrients in the medium???

Lila Stängel - Nährstoffmangel?
Hallo zusammen, ungefähr eine Woche, nachdem die Pflanze mit der Blüte begonnen haben, haben sich die Stängel der Blätter rötlich/lila verfärbt. Meint ihr das kommt von der Genetik (Auto Overdose - Divine Seeds) oder könnte es sich auch um einen Nährstoffmangel handeln?

Red petioles, everything else good
Hi! :) Does anyone have suggestions on the red petioles? They all turned red in flowering week 3, also the lower ones. I removed the secondary shoots and some leaves lately. Nutrition should be plenty, soil pH and EC are normal. temps are normal, humidity in a perfect range...

Red spots
I'm getting some little red spots on some of my fan leaves. Not all but some. Any ideas what this might be caused by? Wondering if it could be pH or either too much or not enough nutes? Thanks in advance.
