The dark green thin leaves lower down - possibly Suplhur or Phosphorus excess. I have never done Autos though, kinda just assume it is nearly harvest time?
Luciditeanswered grow question 4 years ago
If you have flushed then you would expect leaf decline as the plant uses up any nutrients it can. Even if you didn’t flush it could just be one last push by the plant to produce fertile buds. If this happened in week 7 you would worry. In week 12 it is probably normal for a plant that should be ideally at harvest time. Check your trichomes?

Yellowing edges and brown tips in 7 week of flower.Hello, fellow growers. Need some help. I'm in 7th week of flowering and upper leaves start yellow with burnt edges. The lamp was too close(30 cm) for 3 days. I raised it to 50 cm ten days ago, but the symptoms are stil progressing. Is it light burn or potassium deficiency?

Yellowing on older fan leafHey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?

Late flower issues- chop early?Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.
