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!

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!

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.

5th week of flowering Easy Bud, unsure of when and what to do next.end of the 5th week of flowering, the buds are growing but are still very slime but a few of the pistils have turned red. Have some burn on the top leaves, are these going to cause more issues? Are they likely to bulk up anymore? am I looking at another 2 weeks or is it longer?

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.
