What's Going On With These Leaves?

TheDankest · Jan 4, 2025

Any idea what's going on with my main GDP plant? I had this same thing on two of the lower leaves. I removed those two leaves the other day, and now I'm seeing it on these two.

Fox Farms Ocean Forest soil
18/6 light cycle
Light 18" above plants
70-75°F
70% RH
Not currently feeding any nutes
Looked really close at the leaves and didn't see any pests

Currently it's only on these two leaves pictured, and other than that is looking pretty healthy.

In my opinion it looks like it's time to start feeding. Had the same issue with my GDP. Started feeding and few days later they improved and doubled in size

I was planning on feeding at their next watering, as of the time of that posting they weren't ready yet though. Still have to check on them today, going to do that shortly

What do you have for lighting? Looks a bit stressed from high intensity lighting. Just a thought. Is this a cut or seed?

I have an AC Infinity IONFRAME EVO3 - 18" above canopy top, 18on/6off cycle, 80% intensity (as recommended by the user manual)

I've always done 40% intensity for seedlings, 80% for veg, and 100% for flower without any issue

I'd dial back the light intensity to see if its light stress. wont hurt that's for sure. Plus a little stretch might help that girl. Good luck friend.

seed or clone?

TheDankest · Jan 4, 2025

So I have to assume this is the beginning of root rot. I just checked on my main NL plant and I'm seeing this issue on its leaves now as well. When I stuck my hydrometer in the top of the soil, it only had a reading of 3, but as I pressed it deeper into the soil, it was reading between 7-10 at the bottom, and I haven't watered them in a week.

How can I fix this before it completely destroys my plants and the last 4 weeks essentially become moot?

To me it looks like it's suffering from low Phosphorous and Potassium and loaded with Nitrogen.

-Dark green almost waxy leaves is a sign of high Nitrogen
-Tips browning is usually associated with low Phosphorous
-Pitting or discoloration within the leaves is associated with low Potassium
-Purple fan leave stem also points to a Phosphorous deficiency
-Wrinkling is due to watering/nutrient deficiency issues

I think the first person was right.

Fox Farm oceans forest can be a little much for some young plants and is better suited for older plants. Maybe try Fox Farm Happy Frog and use Ocean forest for the transplant. If you are not transplanting use Ocean forest at the bottom of the pot so the roots get there as the plant ages.

Best of luck!

why do you think root rot, ?I think they look good,nothings ever easy

OldOneEye · Jan 4, 2025

Cal/Mag deficiency: orange to brownish spots in the center of leaves
Nitrogen burn: brown crispy looking at edges of leaves.

Because it's showing signs of nutrient deficiencies which shouldn't be the case 4 weeks into some fresh Ocean Forest soil - this should have enough nutrients to get them through the first 4-6 weeks. With that said, root rot can cause nutrient lockout, and make it look like a cal/mag or phosphorus deficiency as others have mentioned, since the nutrient lockout caused by root rot would indeed cause deficiencies.

My #1 tell is that I watered them when I transplanted them, and haven't watered them since. My last post should have said "I haven't watered them in *over* a week". It's been two weeks since transplant, and my hydrometer still shows a moisture rating of 7-10 near the bottom of the pots. I tried switching out the two extra plants I have (showing similar symptoms) to fresh soil and fresh pots yesterday and when I checked them this morning they were dead. Not sure how to save these other two (this GDP, and now my main Northern Lights #10 is also showing these signs) and I don't want the last 4 weeks to be a waste.

Lesson to self for the future: Despite seeing loads of people on here going straight from a seedling cup to their finishing pots, I won't be doing that myself again any time soon.

Check the ph off your run off. Those leaves in the red solo cup say low ph to me.

I won't be able to do this until their next watering, and they haven't needed water in 2 weeks. That's why I'm thinking I overwatered when I went from seedling tray to finishing pots which is leading to the onset of root rot. This is the first time I've tried that to reduce the amount of transplants, but also the last time I'll be doing that for a while.

My friend I am sorry to read about the plants.
Life's about mistakes and learning from said mistakes.

I've had this scare once before as well and switched to fabric pots.

If you are curious,

I use Peat Pot Seed Starters and plant them directly into a 10 gallon fabric pot with moist soil.
I only spray water around the hole where I put the peat pot to help it break down and encourage the roots to grow out.

Now that I'm thinking about it, do the fabric pots help aid in wicking excess moisture from the soil? I would imagine this would also increase the RH in my tent a bit so I'd have to adjust accordingly

Yes they help a lot and do effect humidity greatly after watering.

Gaia Green has a soil made for marijuana that when combined with the fabric pot, you can pretty much never overwater. You do have to water slowly since the water will run out of the fabric pot if that's the path of least resistance. I also start the seed in pure moss in the peat pot.

I've been using a simple drip line IV bag after I transplant to help not over water and then switch to bottom watering after I think the roots have spread out enough.

Bottom watering is a great technique to promote plant health and reduce the risk of common watering related issues.

Over and under watering is the hardest part of growing in soil.
Once that's worked out everything else is simple.

I use and love them. Both indoor and outdoor grows.

I ended up giving them a full dose of Fox Farm Grow Big and Big Bloom yesterday afternoon, I'll post some updates in another day or so
