Sick plant?

[Chavoso013]

Hi guys, this is my first time planting and the first 2 weeks was everything fine. After that both plants that I have started to show some white spots on it. I looked up on internet and saw that white dots can be bugs, which could be a possibility since i plant outdoor in my terrace and I've seen some spiders and etc.. But the only problem is that the pictures in the internet doesn't look like mine. Do you guys can help me? Is that bugs/spiders? thank you guys!!! Can't wait for my 1st harvest!!!

It looks like your growing outside from looking at the images and looking at the marks on the fan leaflets it looks like something could be having a chomp on the leaves so you may need to spray them with some sort of bug spray to get rid of them.

Apart from that your plant looks a nice green colour and its obviously not hungry.

Hopefully someone with more experience will be able to provide better advice.

Yes, the white spots do indicate that there is something eating the leaf.  Most likely spider-mites or small caterpillars or white-flies. The white spots indicate that the pest is eating  or sucking juices from the underside of the leaf.  Either of these pests are difficult to eradicate, but it is possible.

 

If it is caterpillars, you will see the tiny caterpillars and their tiny black balls of caterpillar shit at various locations on the plant. 

If it is spider-mites, you will begin to see fine white webs on the underside of the leaves with groups of tiny orange or brown mites hiding within the web.  If a spider-mite infestation becomes advanced, then the webs will begin to cover the leaves and colas.

If it is white-flies, you will see the tiny white fluffy flies on the underside of the leaves and on the stems, or flying about looking like fluffy white dandelion seeds released into the wind.

 

If caterpillars, you can attempt to locate and remove all the caterpillars and their little balls of shit, but then you will need to treat to prevent their return, because it is nearly impossible to find them all; they hide everywhere around the plant and the pot, in the soil, on the balcony, etc.

If spider-mites or white-flies, such individual capture is not possible and you must treat with some kind of pesticide.

Regardless which of these pests you have, you should definitely do something, otherwise, the rest of the plants in your entire home are in danger.  Keep in mind also, that it is possible that these pests originated from the other plants in your home or garden, so you might need to treat EVERYTHING in order to eradicate them.

 

You can try a solution of Neem Oil.  Neem Oil is a natural pesticide, but normally these pests require something a bit stronger.  In your garden center, ask for a pesticide that is appropriate for the pest that you have.  It is good that your plants are so young.  Using such a pesticide on Cannabis means that the existing leaves should be noted (marked) such that you do not use them in any way.  Only the leaves that grow after the application of the pesticide should be used.  To mark the treated leaves after treatment, simply cut away the outer 1/3 to 1/2 (one-third to one-half) of each and every leaflet.  That way, at harvest, you will know to throw away any leaf that is not full-length.  This is usually not a problem for plants that are so young, because you are not interested in these early leaves anyway.  At harvest, you are wanting to harvest only the flowers and the tiny leaves found in the flowering cola.

Don't worry, cutting away 1/3 to 1/2 (one-third to one-half) of every leaflet will not hurt the plant; it will recover just fine.  In fact, doing so will encourage the plant to accelerate new growth.

 

Do not delay in treating against these pests.  They can destroy the plant if not treated.  If a spider-mite infestation occurs in the flowering stage, then your harvest is basically lost; spider-mites make a terrible mess of the blooms.

 

Normal spiders (any spider that is not a spider-mite) are not a problem at all, because they hunt, catch and eat the pests.  Unfortunately, a normal spider cannot catch them all.  There are some other beneficial creatures that you should allow to remain on the plant.  Lady-bugs (Marienkäfer) are good.  As well, preying-mantis are good if you are lucky enough to have them.  Any form of wasp is good, as they hunt the pests too.  Some garden centers will sell some of these hunters, or you can order them in the internet.

Unfortunately, if you use a pesticide, that will drive away the natural pest hunters.  (Can't keep the cake and eat it too.)

 

Good luck eradicating your pests.

Hello, Thanks alot for the info!

 

I just want to make sure i understand what you mean about what to do with the plant after applying the pesticides.

 

You are saying that once I apply the pesticides to the plant i would have to cut every leaflet one third or one half. That will help me see that when its time to harvest i can not use those leaflets. 

 

I can only harvest leaflets that have not had pesticides applied to them?

 

Do you know the reason I can no longer use these leaflest?

 

Two of my plants are 7ins and the other is 15.5 iniches. Because the other is so big when i  aplly pesticides will it be afftected diffently than the smaller ones

 

Thanks aging for your help and knowladge
