Anyone seen this before?

Hi All,

not 100% sure but looks like a grub or bugs are eating the leaves from the centre and killing surrounding tissue.

To me it looks like necrosis starting around the veins and spreading into the leaf tissue. Bugs that chew leaf material tend to leave clean cut edges in dark green leaves.

Symptoms associated with the veins suggest a systemic problem. Either a nute problem or a plant wide infection. I can't find any pictures of nute deficiency, disease or infestation which look like your photos, so that's as far as I got.

Is it appearing only on the top leaves? Is it local or throughout the plant? Is it spreading? Is it confined to one plant?

That's my best try I'm very interested to know the answer.

Hi Zvuv,
Thanks for the work you put in, it seems to be the top only. The rest of the plant is fine really healthy, as she is young I have only fed her on 50% general fert' and 50% Ionic Bloom, 350ppm total. I have four plants close together and only found this on two diagonaly across from each other, the other two are very healthy at mo' and just started to show pre-flowers.

If your growing it indoors what kind of light are you using? How close is the light to the top of the plant?

look like aphids to me.they leave a straw in your plant wherever they drill it to suck nutes from the plant.I had them a few months back and looked just like that.shake your plant a little and see if you see 1 fly around.then get you a pesticide and spray your plant before it gets worse.

Is it outdoors? If so it might be a mold, fungus, or disease. I've been looking through pics and that's the closest thing I can come up with. How do the stems look?

That looks similar to severe ozone damage. Do you have a ozone generator near your plants for odor control?

Yes it would help if you gave us more information about your grow. Indoors/Outdoors? Soil/Hydro? etc.

Pic 2 looks like possible spider mites

For a simple safe bug killer do this

1gallon water. 8 drops ivory soap <-- has to be ivory and 1 oz of 3% h2o2

I thought the same thing at first but I don't see any webbing. hmm...

Hi All
Your brilliant can not thank you enough. It is an indoor grow, 600w HPS approx 2 foot away from the top of the plants, I can feel no heat there so thats ok. No ozone generator present. But But for a while I had a spider mite problem which through cleaning and soap spraying got rid of them. Had two grows since and not a sign of them. So to make sure I purchased some Diatom x! it's like a dust you put ontop of the earth, the dust is fine and contains silica so small and very sharp that any living thing gets cuts to ribbons crossing it, together with Vasaline around the pot edges just as a back up so to speak. So dust got on to the leaves but I blew it off quite easily these were bottom leaves nowhere near the affected ones. The rest of the plant looks really healthy, stem leaves perfect. They are in a soil perlite mix about 75/25 perlite. Ph 5.7 Feed temp 23c room temp 27c Rh 48% 17Lt pots Autopot auto feed system (been using it a good while) no probs'.
hope this helps you.

Have seen any critters running around your babies?

looks like my broccoli that is in the garden.. beetles have been eating away at the leaves.. look just like what you are showing tho. i would bet you have some type of bug eating your leaves :/

The only bug's Ican see are a few fungus knats flying around.
