I've noticed some yellow spots on the lower leaves, and I'm not quite sure what it is. The first pistils just appeared, and I don't know if that has anything to do with it. Could you help me? Deficiency? Over-fertilization? Have they been burned by direct sunlight? Is this normal? Thanks!

Bonjour Les carences en calcium peuvent pousser les nouvelles croissances (racines ou jeunes feuilles) à se former incorrectement et être déformées. Prévention • Ajouter de la chaux dolomitique/de jardin à votre substrat de culture. • Un pH de 6,2 offrira un meilleur environnement pour l’assimilation du calcium. • Ajouter beaucoup de coquille d’œuf à votre compost biologique. • Lancer une ferme de lombrics ! Le lombricompost offre un tas de nutriment, y compris du calcium. Solutions • Appliquer un booster cal-mag. • Augmenter ou diminuer le pH pour atteindre 6,2. • Ajouter une cuillère à café de chaux hydraté dans 4 l d’eau et utiliser la solution pour l’arrosage de vos plantes. J'espère que cela va vous aidé bonne culture 🤞😊

I had a similar problem around week 3 into my grow which ended up being a calcium deficiency. A steady light feeding of cal/mag straightened it right out.

Is this on Lower growth? If so the plant could just be using up the nutes on that leaf in preparation for self pruning useless leafs off. I wouldn't worry unless it starts showing up on alot of leaves. Your girls look healthy and happy! Check out my first grow for tips tricks and to learn what not to do! Cheers and happy growing!

Hi buddy ;-) don't worry your plant looks great 😍🙏🏻, water the next 2 times with half or a quarter dose :-) 1.4 ec is a little bit too high at this stage ;-) and what is your watering behavior?

Leave's tips color turning yellow Hey everyone, for the past 2 days I've noticed that the tips of the leaves are turning yellow. I thought about moving the light away from the girls, even though I'm using an LED (marshydro ts1000). Can you tell me what I'm doing wrong? Should I also adjust the amount of nutrients?

Yellowing plants Based off week 2 day 7, does this look like an over watering issue or something else? This was the first watering where I soaked their containers. While they were in solo cups I tried to keep watering volume low.
