Do I have to worry?
GrowingGrannieanswered grow question 3y ago
Pretty certain this is Leaf Spot Fungus otherwise known as Rust Fungus... and you'll need to jump on this quickly as it spreads fast... it spreads by spores that you can't even see so don't think you've got any time to waste here... I won't go into all the details of what you need to do as this article is very thorough.. Do give it a read and get going so you don't lose your entire grow...

Good luck!

I would just keep an eye on it. If it spreads then you probably have a deficiency. Also pay attention to where it start. New leave is usually a mobile nutrients, the old bottom one it not.

Bottom Leaves only looking worse for wearHi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.

Brown Spots on LeavesI've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Brown spots on yellowing leaves close to Flush and HarvestI'm at day 69 of my grow. The plant has been getting frostier and frostier, the leaves are starting to yellow, and I'm seeing the first signs of amber trichromes. Today I noticed the leaves are starting to get some brown spots. Should I be concerned so close to final flush?

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼Week 3

Also, I underwatered plant these days and maybe this can be a cause?
