Deficiency?
ThatFcukinChronicstarted grow question 3 years ago
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.

Def a nitrogen deficiency, and indeed like TheUk420Show said a cal/mag deficiency. Look at your npk ratio, maybe there is not enough nitrogen in it.
In this stage you have to give around 4% N, 8% P, 10% K and cal mag around 4/3 %. Depends on if you have a sativa or indica, indica needs more nitrogen than a sativa.

Give her nitro + cal mag .just check water for correct PH so she can uptake all.

First of all its nitrogen and then after that its cal mag they are the most likely suspects i would up your grow feed and then see how you go in a week or so she should strip the yellow leaves and build fresh sets :) prob be the last at that far along in flower :) best of luck for finishing the run :) 👊

Am I overthinking things?Any idea what’s going on with these ladies? Or am I just over thinking. They just seem a little unhappy. Watered 750mil yesterday morning the last time before that was 500mil Saturday night. Could they be a little overwatered?

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
