What could cause this? Outdoor Problem with pics ....

[miaumiau]

after 4 days of rain my plants looked not that good at the tops of the plants, holes in the leafes and a very light green, and they looked kind of "dirty"...

now, after another few days of rain, plants look a bit better at the new growth, but i took some pics of the "brown spots" on the stem and the leafes...

they are 2 meters, i give bio bizz alg-a-mic, bio grow, bio bloom and top maxx every watering once a week



here the pics :

its probably some bug, I got exactly the same problem with mine....tiny little holes in the leaves

 

[miaumiau]

do you have the brown spots on the stem and leafes as well?

 

[Puffster]

some on the leaves, but on the stalks its hard to tell since they are all purple

Look at the thread on leaf spot it could be a type of fungus.

i agree it don,t look like mites or grasshoppers
try spraying it with neem oil or fungicide

 

[miaumiau]

cool, thanks ....i will let you know what happens ....

the stem photos sorta look like Pythium rot. Is the surface squishy where the bumps present themselves? if so, I'd take immediate, drastic antifungal action

Fungus???... nah, looks like the work of bugs ta me. Good luck! BC

I may be loosing my mind but after a second look I agree with BC it almost looks like hopper burn. They usally move on but if not liquid Seven will take care of them.

i think you are right....i saw a few little cicadas, or like you said leafhoppers...but i didnt know that they cause burnings on the plants....only knew that they are responsible for the holes in the leaves...


dont want to spray neem, because plants are in flower for 3 weeks now...hope they push along....but i think the more resin the plant produces, the more uninteresting will the plant be for them.....or better lets say i hope this ;-)

in this pic I see little black/grey spots.....You should use a lens to check below the leaves........

 

[miaumiau]

no no ...definitely no thrips .....;-) have an eye for thrips and mites !


think its not a big problem .....maybe the brown spots are a kind of burning or something like that ....
