Hi all

I've just flipped my cabinet to flower 2 weeks ago, I'm noticing what is normally a nice green leaf starting to have some yellow speckles, some plants worse than others

In vege the plants seem to like a 3 waters with regular tap water to one water with diluted nutes every 4 or so days. But since going into flower they seem to have changed...

Can anyone give me some advise on what I can so to make them happy, should I be feeding more nutes and less regular tap water?

They look like they're starving and have a serious mite infestation.

There has to be all sorts of tiny dark spider mites all over but especially under the leaves.

Do you have any sort of magnifying glass or scope? I can see them with just my reading glasses on. Just stare at a few dark spots and if they're moving around it's most likely mites.

I had a 2 year battle with those little demons from hell and finally got rid of them just a couple months ago. The last two days I spent almost 20 hours working in there repotting and snipping out any bad leaves and went over the plants with a fine-toothed comb and not a bug to be found. Got a nice little magnifier app on my Android phone but have a loupe. 30X scope and a USB scope good for 1000X.

I just clicked on your bottom pic to see it blown up and I can see the f'ers on the leaves!

Die you bastards DIE! FiringCat.gif

I got rid of mine using Safer's End All II with 10ml of canola oil added to each 1L batch I mixed up from the concentrate which makes 10L for the price of 1L of the same stuff pre-mixed. You're going to need a few liters. Most anything you use is going to leave residue on your buds but they are small yet so if you get right at it it shouldn't hurt. If you don't get right at it your plants are toast anyways so you got nothing to lose but your crop.

Plants eat up to 4x as much during the stretch after flipping to flower and it doesn't sound like you were feeding enough when they were still in veg so you best feed them ASAP. High P/K but a good dose of N is what they need. What are you using for nutes and please don't say Miracle-Gro. ;)

Good luck. You're gonna need it.

:peace:

Oh no... Yes your correct I pulled it out to have a look and there's spider mites on top and eggs in the bottom of the leaves... Im in newzealand so I'll need to find a product I can buy here...so will the mite kill all my plants or just make them struggle a little are they really that bad? (I'm really stressing now) Im using the product in the below pic for nutes I'll up the nute intake. From now on.

I've turned up the fan and I will get some Yates natrasoap tommorow.. That's the closest thing to what is on the list of stuff that works.. It seems hard to find newzealand equivalents of alot of the products people on ROI recommend.

That oil seems to be good for mites and it's in an emulsified concentrate so should work.

You need to soak the plants really good. I start by picking off a lot of bad leaves first then lay the plant on it's side and starting at the bottom spray the crap out of it. Wear a latex glove or not and run your fingers thru the leaves making sure you don't miss a spot. Turn a bit and keep doing that until you've gone around the plant then stand it up and make sure you cover the tops well. Use you spare hand to keep moving the leaves around as you go.

Skip two days then do it again for a minimum of three treatments. I did four just to be sure and it finally worked. I wasn't consistent before but that time stuck to the schedule.

With every leaf already spotted it's going to be hard to do follow up checks after all the spraying is done.

They are horrible pests and the bane of pot growers everywhere. There are even worse mites that are near impossible to get rid of but I'm dead tired after two hard days in the grow room and can't recall the name atm. Tomorrow they start 12/12 under an insanely bright Hortilux 940W conversion bulb riding on my Light Rail. Had to set that up too along with shifting the rail a foot wiring up the remote ballast etc etc. lol

That soap sounds good and seems to have vegetable oil already added. Most likely canola oil. Basically the same as what I used except mine has some pyrethrum in it too.

Passing out here so got to hit the sack. That last couple tokes did me in. pass.gif

2:30am here.

More than welcome.

Forgot to mention.

Those nutes are pretty basic and fairly complete but not very strong so give them a couple of full strength feeds in a row.

G'night.

Having experienced a similar infestation of spider mites, I can tell you that they will impact your yield. With that much damage, your plants will suffer.
You will still get buds, but I wouldnt expect large kolas. Your yield will be significantly less.

I used a product called mighty wash wash to get rid of them.
I removed all unnessary leaves, hung the plant upside down and sprayed all the remaining stems and leaves.
I turned the plant right side up and did the same...spraying from various angles.
I repeated this every 3 days for 9 days.
Oh...I also sprayed the walls of my tent.

Your plants are young.
If you have more seeds you might consider just torching them and waiting a month(for any living bugs in your environment to die) and start over.

If you dont attack them agressively, they wont go away.

Thanks for your info.. I have one plant affected out of 8 so not keen to torch.. I have sprayed and cleaned all of the plants... Apart from a couple of clone experiments all of the plants are around 6 months old and I've only just flipped them... Im really hoping they will be ok with a few treatments.
