1st grow yellow leaves and brown spots

MrBz21started grow question 5y ago

Last two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(

This is normal mid to late flower. I would check the ph situation and up the feeding of your bloom nutrients. All the best!

I would personally before adding anything else water until you have enough run off to check the Ph often deficiencies come from pH fluctuations causing nutrient lock out 💚🌱🙏

If this was yours, how would you proceed?Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?

Deficiency help What deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think. Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.

Plant issues... How long to harvest?Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!
