witting and curling down and inward after neem oil

[nzl]

Hi can someone tell me why my leafs are all witting and curling down and inward after neem oil was used to combat spidermite?
I mixed the bottle up 4ml /500ml water and mist it on the plant.
It witted 12hrs after the application. Im in 4 weeks veg, ak47.

I have since gone down to my local grow shop. the guy told me to wash the plant. can some one tell me
1)- when will my leaf return to normal
2)- how do i prevent leafs from witting /curling inwards using the same treatment
3)- should i use neem oil again
4)- how often should i clean the plant now after my last application
5) how much damage have i done, if any or heaps?

any help will be great

I really doubt that its the neem oil. Many gardeners including myself use it all the time. It perfectly safe, as it's not a nutrient foliar feed.
Look at other sources of trouble.

How bout some pictures...

As for them returning to normal. I think it will depend on how much damage is done, and the strain. Lord knows Ive used too much foliar feeding burning and shocking the leaves.

Ive jacked up my plants after changing the entire nute regime. I adopted some pretty big "clones" and the baton was not passed well. They went into shock, including many damaged leaves. But I have a good environment and that made all the difference. Now I'm rocking some pretty sweet nugs.

Do u wash the leafs after u foilar with neem oil?
the reason i think is neem is that everything was 100% then after the neem application its witted straight away.
Im in soil and using organic fert only

Umm... one time I covered a few leaves with 100% neem with my finger. They did not seem to mind. Look, let's say that it's a problem... Do you think that your solution will make it better?? Water won't wash away oil. And any oil or alchol based anything will make things worse. I would just try to remove as much as I could with some charmin tissue paper.
Neem is not toxic to your plants at all. If anything it's just sufficating the leaves.
Next time research the excepted application method and recipes. You can't just go about this willy nilly. I use the rule that I research minimum 1 hour before trying something new. And never trust a single source, ever. Grow with caution.

Yeah your concentration was too high. I use about 4 ml per gallon, so yours is 4X that. Rinse with ph'ed RO water a few times and they might recover, but then again they might not.

use some kind of liquid soap or a surfactant like SM-90 to help the neem oil mix with the water better... oil and water doesn't mix on its own

thanks guys. Im getting a feeling attila76 you dont think it the neem. what do you think it is? I dnt think my plants are dying but it looks like the leafs are suffocating. Theres new grow but man the plants are weak. The leaves are witted as hell and not holding their shape. Im not happy at all ae.
Lazyman- How often would you recommend washing the plant. And whats RO water?

Reverse osmosis, or use the good bottled water. As mentioned above, SM-90 is good for neem applications too, coriander oil is something bugs dont like and it helps sprays stick. I'd spray them with plain water, phd to 6.2 or so, and hit them twice a day for a few days if you're not past week 3 of flower.

thanks man i really appreciate all your help here. Im going to get some bottle water. I may also do a wash with warm water aswel to see if that would help wash it off. Now should i wait for the plant to come back first before i do another neem application. I know i will do a less concentration too. the bottle say every 2-3days for 2 weeks.

Instead of neem for spidermites, go on ebay and order up an ounce of floramite sc. Trust me, 1.2 ml per gallon, in a foliar spray, every 3 weeks = no mites.

It's not so much that neem oil is toxic to leaves, but that any oil blocks transpiration. A rinse a few minutes after spraying is always a good idea. Some locals here have been getting better coverage by applying the oil water mix to the leaves by hand. I've noticed that mites prefer the undersides of the sunleaves to any other location, so I concentrate my battle there and ignore leaf tops and buds. By keeping the population on leafbottoms low, they don't move to other locations. Also, by only wetting the bottoms of leafs, the whole topside is still clean for transpiration and chance of damage is hugely reduced. The best method for smaller plants is dipping. You can dip in a stong neem-water solution, let sit a few minutes and rinse in straight water. For large plants in flower, you can hold a bowl of solution in one hand and submerge fan leaves one and a time, and follow with a rinse.

The real key to battling mites is some kind of therapy or meditation. Seriously though, continually trying to 'wipe 'em out' will make you crazy, better to figure out solutions for keeping them down and weak. Learning to live with mites will actually make you a more effective combatant in the long run than always chasing dreams of destruction.
