Tips burning, brown spots
Anorakstarted grow question 3 years ago
Hello growers! I have White Widow in the 5th week of flowering. Only top leaves are affected, some of them are turning pale yellow. Feeding her with NPK:18-12-18 and Cal-Mag. The brown spots are my biggest concern.
THANK YOU!!

Seems like Excessive nutrient + Light burn(and maybe excessive heat, but it could be due to light exposure), a hard combination that one make the other worse.
Check for light proximity, and if you use fertilizer take a time without, with only water.

It looks like nutrient burn with a slight lock out issue going on. Lock out could be from PH being off so check that and also get the nutrients down. If grown in soil I would “soft flush”.

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

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!3 months ago

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?

Yellow leaf tips in flowerShe's pretty far into flower, in DWC, and the environment and nutrient schedule have stayed consistent for a while now. I'm using GH Flora Trio at 5ml of Micro, 2.5ml of Gro, and 7.5ml of Bloom per gallon.
The leaf tips are looking burnt, should I ease off on nutrients or what?
