Purple branches Hey, many of my branches have turned purple, and a few leaves yellow.... I'm using bio grow (biobizz) since 5 days, is it calcium or magnesium deficiency? What to do? And can I start with flowering now? Thanks

PLEASE HELP! See former question as well.Continue to see deficency or burn in leaves. I have fed her only ph water for 2 weeks and it continues. I asked for help before, everyone just tells me what they think is wrong and not the reasons why. If you have an answer it would be appreciated to know your reasoning. Thanks🤘

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 🙏

Nutrient deficiency? Or just getting ready for harvest? Sister plant is very green (different strain, strawBerry cheesecake, last pic)Plant is Raspberry Kush, I’m assuming it’s because she is close to harvest and it’s sucking all the nutrients out. Also, looking up other raspberry kush diaries i’ve noticed they tend to end up pretty yellow. Was fed bloom nutes yesterday but noticed lots of yellowing today.

Nitrogen deficiency but why?My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Leafs looks bad. What's the problem?Hi. I'm a beginner and this is my first grow on coco coir. 2 of my plants having problems. I'm watering about every 2 days with half amount of nutrients, that the nutrient company is showing on their chart. So i'm not sure, if it's too much nutrients or not enough nutrients.

YELLOWING LEAVES HELP! I am super, Not Happy, about (what I’m assuming is), Light Bleaching. Everything I’ve read points to Light-Bleaching. In every post I’ve seen, “Nute. Burn” has fairly distinct “burning” & crispy edges around the leaves.

Yellow sugar leaves I am waiting for a low-THC strain to develop amber trichomes and I found two buds with these yellow sugar leaves. There is no bud rot, should I wait longer to harvest? Also, do CBD strains develop amber trichomes, or should I harvest now? Additional details available in growdiary
