Yellow leaves
MrBlocc420answered grow question 4 years ago
Looks to be a manganese deficiency, Leaves may become yellow in between the veins, with mottled brown spots on the affected leaves. These brown dead patches may spread and eventually kill the leaf. Leaves may also shred and fall apart.
Overall growth of the marijuana plant may be stunted. With a manganese deficiency, the yellowing will begin at the base of the leaves and move outwards towards the tips.
Check your ph run off to see if its in proper range . To high or to low ph will cause this problem. Hope this helps you . Good luck to you

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.
