Unknown yellow spots on lower leaves?
GMSgrowsanswered grow question 4y ago
Older leaves do whither and die. They will help supply other parts of your plant with nutrition. It sucks the life out of them so that other leaves may thrive. Be careful on using full strength nutes. Over feeding is very detrimental to your plants and if they do get overfed your nuggies and overall harvest will suffer. If your following the fert label for feeding, just go half. Cheers

Yellowing, wilting, stunted growthCan anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?

Sénescence ou manque d'azote en phase de floraison.Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏
