Leaf Problems... is this Cryptic?

This looks more like a genetic mutation or early stress issue than a virus. Possible causes are unstable genetics, pH/root zone problems, or a micronutrient imbalance. Since the sister plant looks normal, it’s likely specific to this phenotype. Keep pH and watering stable, avoid overfeeding, and use light CalMag if using soft/RO water. If new growth improves over the next weeks, it should still grow fine.

hI Chucky....... Das ist kein kryptischer Virus sondern ein Cal-Mag Mangel....... Gebe einfach Cal Mag nach Düngeschema hinzu und dein Problem ist behoben...... Kein Grund zur Panik.....😎 Viel Glück

Hi I would rather think probably not a virus. generally Actual viruses usually render the plant completely sterile, with extremely fragile stems that break like glass and a complete loss of vigor within the first few days. Here your plant grows, produces nodes and develops roots. I would say more genetics ​ Leaves growing crooked, twisted or with a rough texture are very common on some modern hybrid seeds especially if its sister is doing well. It is often a simple birth defect in the seed embryo. I hope this will help you. have a good evening and great cultures.

Sieht mir nach Mosaik Virus oder ähnliches aus .ich würde die gesunde mit Wasserstoff peroxide einsprühen und die befallene entsorgen. Den growroom auch einsprühen. Calmag kann ich mir weniger vorstellen aber bisschen geben schadet auch nicht. Viel Erfolg noch

Some seeds are just duds...............this is why I always advise not to grow "maybes". You have had problems since germination...............this should have been enough of a warning that "something is not quite right" with this one. I would suggest cutting your loses now and saving your sanity.

Not cryptic virus. Cryptic would show mottling, mosaic patterns, or severe necrosis. This is just genetic mutation or early stress creating deformed growth. The plant is green and growing despite the weird leaves. It’s a weak phenotype from the seed, not a disease. Keep it separate from sister plants just to be safe, but it’s not contagious. Let it finish and move on.​​​​​​​​​​​​​​​​

u had P deficiency but lately u fixed it so the real problem is Ca/Mg income these fucked up leaves and interval chlorosise give u a hint First check ur Ca ppm in tap water if it's 140+ and ur ferts also has some Ca then it's locking Mg 👈 if not which i doubt u just have Mg deficiency
