what a deficiency is this?
BrieflyGrowinganswered grow question 3 years ago
Hi Bud! I used exactly the same BioBizz nuts and soil in my first auto grown with RQS seeds and had the exact same issue. Exactly the same spots on the leaves...
So I can say I'm 90% sure it is a Calmag issue. I solved it by adding CalMag from BioBizz to the feeding with their recommended dosage = issue solved.
My water is pretty soft, around 50/70ppm so almost no Cal or Mag there, so pretty much expected.
You are pretty early on the flowering stage so if you act now I don't think it will affect your yield. Good luck!

Looks like Cal/Mag to me
And some Cal/Mag maybe cut back on H2O

It does look like calcium to me.
should add in some CalMg, should not need to much as you are in soil.
Its also beneficial to let BioBizz nutrient mix sit up all mixed up for 12 hrs to left the PH drift then adjust if you need to.
It can go all the way down to 6.2 in soil and still have good results.
Good Luck!

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?Leaves. Color - Red or pink

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Yellowing and Reddening of older fan leavesI’m experiencing a lot of yellowing that progresses into dark red blotches. I suspected a possible cal mag deficiency but after upping the dose multiple times I’m still having issues. Any recommendations on possible causes/treatments? Temp stays between 74-76, humidity around 60%2 years ago
