Newfie420CBstarted grow question 5 years ago
Having a problem the leaves seem to be rusting out. I had a spider problem in week 5 and this plant was affected the most by the pesticide i used.

Make sure you only apply the pesticides during lights off.. if you were growing hydroponics, I'd suggest pressurized cold water spray for the mites, they fall off in the cold, and the pressure knocks the eggs off.. very in safe pesticide water is.. rusty leaves may be burn damage but it might be a pH issue as well as a calmag issue, need better pics to tell. Cheers

Your plants are showing a shortcoming.
I would flush them 2 timess with normal water. And then start giving some nutes again.
Or i would give some calmag just to be sure.
Happy growing

End of Cycle or something to be afraidHi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today).
I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes.
What do you think?Week 6

Potential bud rot?My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early?
I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!2 years ago

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?2 years ago
