Plant Problem and Diagnoses w/pics

Guest

Recently I have had a round of plant trouble...
After months of tweaking my soil, water, lighting and ventelation, nutes, PH and generally pulling out my hair, I chanced across the culprit one day looking at leaves under the microscope... a tiny amber colored arachnid crawled through my field of vision... Oh no!, frakin' spider mites...

I had been looking at photo after photo of plant problems for quite a while... never saw what I was looking for... so here is a series of photos of the progressive damaged caused by the little sapsuckers...



This leaf is showing the beginings of what I had mistaken as a nutrient problem, purpling veins, Clawing, yellowing tips...
Examination under a scope found a few mites feeding in the area where the leaf blades join together, and one or two mites on each blade.




In the second pic, you can see the damage progress...
under the scope there is now a colony of mites grazing their way up each blade, feeding especially in the veins. several were found wandering the blades.



The damage progresses farther, P?, K?, Mag?, no mites.
under the scope the leaf is now infested, the veins being overrun with feeding mites.





These last two pics show the final condition of the leaf.
The yellow one is overrun...
The colony has abandoned these dry leave, to infest new healthy feeding grounds...
 

So Quick

This is the info I find on the two-spotted spider mite...

Tetranychus urticae, also known as the twospotted spider mite, is commonly encountered on house plants. Spider mites are pests of cultivated plants, and are most likely encountered under dry and warm conditions. When mites are very numerous, they produce a silky webbing covering infested areas and extending from leaf to leaf to cover the entire plant. These mites suck out plant juices.


These look more like the mites I have...


but their bodies are more amber colored...
I have seen no webbing, even under the scope...
But I have seen them feeding...
and the more there are, the worse the leaf is...

I applied neem oil, and the next day could find a few dead mites, but most were still crawling, and feeding...
The following day, 60 % of the mites I find are not moving...maybe the rest will be dead soon...

further research has led me to believe that I have either the european red mite or the southern red mite...

Update: I have view several leaves of different 'infested' plants, and the only mites I have found are corpses... There are still quite a few eggs visible... don't know if the neem killed them, but will be watching them, and will update later...
looks like I may be winning the 'mite war'...

I have watched them through the microscope, crawling, feeding, and laying eggs... creepy little buggers...
They, however, are not the typical mites one sees on cannabis, not spider mites at all I guess...
Visual inspection of the mite and research of many pics on the internet lead me to think it is one of the varieties of red mite.

hi at all...
i use with very succesfull target a combination mix of NEEM OIL and BRIMEX concentrated plant excract ...it kills and prevent all attacks of mites(the big ones and the small ones)..i've tried before with chemicals(difenol) without to obtain as good results as using this MIX..believe me!!
i spray mine plants with 4ml\liter of neemoil + 15to20to30 ml of brimex \liter
..also the sylicates can make a good care for this type of diseases cause bring healtness 2 ur plants..
sometimes i use as prevention a plantcare homeopatic from HUMACULT...especially suitable for cannabis ...is working as a up-stronger on plants structure..but i don't know the composition ingrdients..

just my 2 sesterces.....eheheheeheh

I have fought mites in the garden for years. I consider myself luck just to keep them in check. Everything I try works the first feew times. But the mites adapt. they are the second worst threat to the garden. The first is ME! I just cant leave them alone.

Good luck fighting the little sapsuckers.
