Any problem that caused the rust/brown spots may be gone.

Are you running an air stone in your hydro tank?

Check the pH between top ups and completely empty your tank often rather than topping.

The only hydro I've done is in coco so I can't offer much.

Looks like a PH issue from here, Leaf Septoria spots are round often with a pimple and a dark spot in the center (that would be the spore). So what PH are you running? Are those rocks coco? IF so were they treated/prepped before the grow?

It's hydro. I suspected of calcium deficiency before and was already using calimagic which I upped a bit last time, this is my last refill breakdown (PH 6.00):

Veg	7.58	L		Start	6/26/2023
				Days	27
				Target	80
				ETT	53
Micro	4.93	ml
Gro	4.93	ml
Bloom	4.93	ml
Cali	9.86	ml
Sweet	5.33	ml
Guard	4.00	ml
Silica	5.69	ml

For me it looks more like Leaf Septoria https://www.growweedeasy.com/cannabi...-leaf-septoria trying to confirm

Thanks for the LST advice

I think you do have a nutrient problem that is likely because of low pH and may be made worse by your environment and watering schedule. Whatever is going on is showing as a calcium deficiency in the leaf and I suspect may have been around for a while.

Additionally you need to be disciplined for torturing your plants like that. When you LST don't wrap it around the leaves like that, just the stem. You're creating hot spots for disease and pests doing that.

I assume you are growing in coco. Is it recycled?

If so give them a good flush with nutes in your water with a pH of 6.2. You can add a suppliment like calimagic.

Raise RH to about 60 if you can. Temps are pretty good

Hi all, my second time growing this auto strain - Magnum. Didn't face many issues during the first one bit the current grow is presenting these spots which are kinda weird as it doesn't seem to be a nutrient issue, following Nebula's schedule. The plant still looks overall pretty healthy and the spots are starting from the bottom leaves. I'm growing indoor hydro, temps running from 76-81, humidity 43-48% at 27 days. Topped and LST.

Any ideas?

One needs to go by the watts pulled from the wall not the spoof watts.

[Rwise]

Yep only 90 watts!

BLOOM PLUS LED Grow Light BP 90W 2x2ft, look into Mars Hydro and Spider Farmer.

[Bluey]

You need to do more research on lights and what you require. The light you refer is not 1000w.
What size is your grow space?

[Rwise]

Maybe Praying Mantis would go for them.

I beginning to wonder if you intend on doing a good grow or just kicking cans.

Tf you mean? Im trying to complete a first grow. Im still learning the ins and outs of this

I would think ladybugs eat bugs smaller than they are.
Predatory wasps lay eggs inside prey much larger than they are.

two-marked treehopper, Enchenopa binotata

Things are hopping


I found two of these on the outdoor plants today. Couldn't find much on cannabis related except that it causes damage to stems. Anyone have any wisdom to share? I also found some leaf hoppers. I was considering lady bugs if this keeps up. do they eat tree hoppers also?
