Help: Tip burn from Neem oil treatment.

Hi everyone.

I followed the neem oil treement 8ml per liter in the GrowFAQ https://www.rollitup.org/view.php?pg=faq&cmd=article&id=346 and used Dr. Brunners soap 50ml per liter with 100% cold pressed organic Neem oil to spray down my plants. Fortunately I decided to test it on one plant first. And see what happend 24 hours later: Ahhhh the tips of the new shoots are dying.... I did apply it like 30 min before lights off and also sprayed it down with straight distilled water afterwards. Any suggestions? I read neem is systemic so I could just water my plants with it right?

Any suggestions appreciated!

Cheers

hmm i regularily use neem oil spray and it works great with mine..

i burned 2 of mine badly with neem, i think you need to wash it off after you use it like couple hours later.

I burned a plant just recently using neem too. I sprayed her down at 2 weeks female but i never sprayed it off afterwards.
I do now though. Pics are 6wks fem.

Im using neem py, i wait for thelights to turn off then spray them down, I noticed with even 10 min of light the oils dry to fast and burn the leaves. 30 min is WAY too much light of hps regardless of what the bottle says. I dont even rinse and have no problems with burn.
