Hi there,

Not sure what went wrong there seems to be small yellow dots on the leaves.

 

My system has been running for about a year and i checked the nitrogen level its high.

 

Hope someone can provide me with guidance on what i am facing with.

 

thanks

Hard to know with just those two photos and only the info that it is a mature system with nigh nitrogen.

 

How bout the results of a complete round of water tests as well as temperatures and what climate you are in/season or if it is indoors.

 

Have you ever added trace elements by using seaweed extract or sea90?

 

What kind of plant is it?  And are all your plants showing this problem or just the one variety?

Hi TCLynx,

 

The temperature is around 34 and i am in Malaysia so its hot all year round and its in a green house kind of environment.

 

No i did not added seaweed extract and this is a Choi Sum. However it has been showing in other plants as well.

Are you not experiencing some insect feeding damage? The image is a little out of focus, but looks a lot like leaf hopper feeding spots.  The insect will be on the bottom of the leaf, and if disturbed, fly of rapidly but in a funny arc into some other part of the plant bed. They can cause significant damage

I did see some small white stuff around that area. What are those? could those insects be the problem?

[TCLynx]

Yea, I think I agree that those spots do look a bit more like bug damage than anything else I could think of.

Perhaps some sticky cards are in order.

[Teh Teong Chian]

I see. Anyway to get rid of those bugs without chemical usage?

This might help, not sure how well they work against leaf hoppers but they definitely help against some things.

Allright. Thank you soo much for the guidance.

 

But is this serious if it goes on?

[TCLynx]

I don't know seeing as I no longer use a greenhouse, I generally ignore pests and I usually still get some produce.  However some types of pests in a greenhouse can really get out of hand since there are usually not enough natural predators to keep them in check.

Alright then. Thank you soo much for your response.

If you leave them, they could cause a bit of damage alright, but they will not kill a plant.  The sticky traps and manual "find and squash" will both help sort them out.  I accidently introduced some with flat-leaved parsley plants I bought, and it tool a while to get rid of them.  Most sprays or oils will not work so well as they are typically on the underside of the leaf.

I see. Ok then as long as it wont kill the plant i think i can bear with it.

 

Thanks Kobus
