yellow leaf, brown spots deficiency
Beans416answered grow question 2 years ago
Hey it looks like nitrogen deficiency. Buds are taking nitrogen from the leaves and not the soil.
Hope this helps happy growing.

Another thing to look at is where/what. Where/What leaves are affected. Old/bottom or new/top. My guess is N, P, and K, unless you have re potted recently.

Light colored sugar leavesI'm at the end of week 6 and the plant is looking healthy overall but there are some bud sites that have some sugar leaves that are developing with a lime green color. Im thinking I might have been a little high on the ec so I backed off a couple days ago. Thoughts?

Rate the Bud - 6 Week completed floweringSo this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning.
On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Do I have an (Mg) issue?Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?

Cut off yellow leaves.Can I cut off these leaves?
I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.

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 🙏

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.

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, whI'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?
