Yellow spots on leaves
FunnyWolfstarted grow question 1y ago
Hi, I've noticed these spots on the leaves, does anyone know what they are please? Leaf Septoria? I hope not.
It's a soil culture under leds, I used Biobizz products (Bio grow, bio bloom, top max) with biobizz calmag, I adjusted the ph to 6.5 with biobizz bio down.
Thank you,

I suspect there is a calcium deficiency. I would lower the pH to around 6.2 and maintain CalMag at 1.5 to 2.0 ml per liter with every watering

Hey! Leaf Septoria typically shows as yellow or brown spots with dark borders, often starting on older leaves.
Since you’re growing under LEDs with Biobizz products and a controlled pH, fungal issues like Septoria are less common indoors but not impossible if humidity or airflow is off. Also, nutrient imbalances or pests can cause spots too

Deficiency or toxicity?Hello i'm not sure what's going on, is this toxicity or deficiency? She loojs happy overall but new leaves have weird color, curled down tips, some of em are yellow and some are brow - burned.. maybe it's because she's transforming into bloom phase, PH 6.2 but runoff is PH 7.1.

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answer

Weird burnThought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light SoilOn my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Leaves are drying up and turning yellowHello,
Something bad is going on with my Hulkberry plant. I think it might be due to giving it to much fertilizer.

As you can see, the first two plants look quite good while the last two leave something to be desired. The leaves on the back left are curling downward andand yellowish at the tips (in places). What could be the reason? I ordered some epsom salt to try it out (sulphur). I grow in floragard proffesional growmix (grown in lightmix from biobizz) and have so far only “fertilized” with supervit, otherwise only pH-adjusted water. pls hlp
