Curling plants - disease?

[billbob]

My plants started curling. I flushed and then fed a light solution for days along with more flushing. It seems like it is speading like a disease. My feeding is dtw. Plants are fed from 3 separate res and on 3 seperate tables but all show similar signs. They are in day 15 of flowering. The new growth is light/yellow in color and new leaves are distorting. Been going on for about 10 days and just seems to spread. I used some bayer soap on them thinking it could be root aphids or something similar. Any suggestions appreciated. room temps and humidity are all normal.

I have never had this issue before and have changed nothing except i took some clones in from a club i had never used before. they were the first to get sick.

phos can be toxic...

Check for broad mites. 100X scope. Look under leaves for eggs. Cut off some affected leaves and scope carefully.

Looks like mites to me. I fought what i thought was nutrient problems, light problems etc.. I checked, double checked and triple checked everything. In the end it was mites. Depending on which variety you have they can be tough to get rid of. For sure get a magnifier and check both sides of the leaves for any sign of eggs or bodies. If you have Cyclamen mites they are very difficult to see (and just as hard to get rid of) with anything less than 50x and then you will only see the eggs as tiny little clear dots.

That looks just like Broad/Cyclomen mite damage. As said before, they are very tough to get rid of, and they secrete a toxin from their saliva that builds up in the plant. Even if you get rid of the bastards, their toxin is still there.

I lost about a year of productivity to those little f*ckers until I figured out what they were. Here is a pic to let you know just how small they actually are. (They are clinging onto the leg of a white fly!) They are about 1/10th the size of a normal mite.

Ultimately I had to scrap my plants and start fresh. I lost some really nice genetics due to those bastards....

There are ways to get rid of them if you don't mind using really harsh chemicals, but even those aren't necessarily 100% effective, as I believe the mites are starting to gain a resistance. There is a stickied thread devoted completely to them. I highly suggest you read it. These things really are the worst thing I have ever encountered in my room.... Do not take it lightly! If you do plan on fighting them, don't even bother with over the counter remedies like neem, pyrethrin, spinosad, potassium salts of fatty acids, azatrol, etc... None of them work. They might knock them back a little, but will never kill them off completely... and your yield will suffer tremendously the whole time they are there. Over the course of a year, my yield went from 90%, to 75%, to 60%, to 40% and finally to 20% of normal before I finally scratched the plants, nuked the room, and started over completely. It was a bad year!!!

Anyway I am not trying to scare you. I am just trying to convey the gravity of the situation if it is indeed those little bastards. Don't mess around with them!

You are in flower, so you cannot use miticides. Your only option is a heat treatment, but from the looks of those plants, you have waited way too long to start treating. The toxins have already done their damage, and more than likely those plants will be duds no matter what you do at this point. Heat treatment will kill mites on plants and in the room, which will be a recurring problem once they are in your environment.
By the way, the person neg-repping me is super douchebag Storm Shadow, who has been stalking me and neg repping all my posts. He sells poison weed and should be locked up for poisoning people. Why he hasn't been kicked off the site is a mystery.

Do U have a lot of calcium in your water I seen cal. make leaves curl ,, Or You may have a bacteria in your water system . OR you could also have some mildew problems . Powdery starts to show up around that period of flowering sometimes . hope u solve your issue.

Retro, a little positive rep to counteract the negative

thanks for the replies.

No PM and everything was eagled in veg.

There are a few mites but really only on a few plants. Been treating with azamax. the plants in the picture im 95% sure dont have mites. I will look good tomorrow with a scope. I have seen them plenty and am very good at spotting them.

Water is ro and i add 3ml per gallon of calmag

Yeah, Storm Doucheboy neg repped me again. Surprised admin doesn't just kick that ghetto dog to the curb. He's been trolling me for a year now. Neg rep from him is actually a compliment, as he is nothing but a gutless hood rat. He also has multiple accounts here, to spew his venom.

A "few" mites is a few too many. You are only seeing a fraction of what's there. You will see plenty of eggs under affected leaves.
