Does this look like nutrient burn, or a deficiency? The PH is right at 6 and I did my nutrients for 3 gallons in like 4 gallons of water.

Hi, your plant is hungry, are you giving all micro/micro nutrients needed. Defo showing deficancy of nitrogen possibly Calmag also, the new growth is looking better already, ✌️💚.

I remember your earlier question about General Hydroponics / Terra Aquatica, and from your setup it really looks like a DWC system with just a thin layer of hydroton on top. This doesn’t look like nutrient burn — it’s more like a nitrogen deficiency. The pale color and the lower leaves yellowing upward are classic signs of low N in hydro. For DWC, the ideal pH is 5.8. I’d lower your pH to about 5.8 and keep it in the 5.5–6.0 range. That’s the sweet spot for nitrogen, CalMag and micronutrient uptake. Your EC also seems a bit low for Terra Aquatica in veg. A good range in DWC is EC 1.2–1.6 depending on the strain. Slightly increasing your base nutrients or adding a small amount of extra nitrogen (like a mono-N product) should fix the deficiency quickly. Your problem might even fix if you go by the standart scedule given bei General Hydroponics. By carefully the bottles shows a scedule for Terra/Coco and one for Hydro. Don't switch it up... =) And for your former Question on General Hydroponics..... on the European markets they go by the Name Terra Aquatica. Same product/producer, diffrent name. But you'll finde Terra Aquatica in the list. 😉

Auf dem Bild sehe ich, dass die Pflanze in Tonkugeln (Blähton) steht und deutliche Anzeichen einer starken Unterversorgung aufweist. Das ist kein Nährstoffbrand, sondern definitiv ein Mangel. Das Problem: In Woche 2 hat die Pflanze kaum Reserven und braucht dringend Nährstoffe. Die gelben, hängenden Blätter zeigen einen Stickstoffmangel. Bei Hydro/Blähton muss man von Anfang an düngen, da das Medium keine Nährstoffe speichert. Meine Empfehlung: - Sofort mit einer leichten Nährlösung beginnen (ca. EC 0.8-1.0 für dieses Stadium) - pH auf 5.8-6.0 korrigieren (du hast 6.0, das ist ok) - Die Pflanze erholt sich schnell, wenn sie Nährstoffe bekommt In Hydro nie "vorsichtig" düngen - die Pflanze hat sonst nichts! 💚

Stehen die komplett in diesen Pebbels?? Aber das ist ein Mangel im Endstadium. Da fehlt alles an Grund Nahrung
