I moved these 2 plants from a grow cabinet I had in a garage to the flower room in the basement. and I noticed a couple days ago a few spots on a couple leaves. I thought it was bugs so I have been spraying with neem oil.This morning it spread to more leaves and now it is taking over the plant.
It is 83 degrees and 55% humidity.
In soil, using GH 3part +calmag,liquid karma,hygrozyme. watering with this every 2 days.
Sure that's not just scarring from the previous damage?
Are MORE leaves affected, or is it just the SAME leaves looking worse?
It looks to be both, the existing damage got worse and it spread to more of the plant. I actually don't think it is bugs any more. I think it is nute lock. Lights are off right now so I have to wait about 1/2 hr. But last night all the new growth looks to be shriveling up. I used straight water from the dehumidifier yesterday so I hope it looks better today, but I think I may need to flush more. I'll get new pics as soon as the lights come on.
I wonder about your neem oil application.
Do you get drips, or do you mist so lightly that it simply coats the leaves? Do you ever see droplets?
Neem or other oil suffocation symptoms can be hard to recognize until you see them for the first time.
I tried not to spray too much of the neem. I didn't notice any dripping but the leaves were coated. What would be the solution for that?
Here are the pics from today. It looks the same as last nite.
The leaves should be coated, but only lightly so. The finest possible mist you can get.
Something funky is going on with the new growth. GH 3-part... hm. What's the pH of your fert solution RIGHT before application?
Fill out the troubleshooting form completely and let's figure this out.
I've been keeping it right around 6.0 but I am waiting on a new probe for the tester.(it would not calibrate)It should be in today I hope. I misted the leaves today with rainwater and moved the light up a little, but I don't think the problem is heat from the light.
I'll do the help form a little later, I have to go do a couple side jobs. Thanks for all your help
How often do you mist with rain water? I think we may have found your problem on both counts. Did you know that water, rainwater ESPECIALLY, can leach nutrients out of the leaves? That would explain the pale new growth, and water beading up and burning under the light would explain the rest.
Indoor, under 400w HPS 12/12 for 5 days so far, in soil, just flushed with rain water then repotted in 5gal bucket with existing soil, added 30% perlite to older potting soil. Rainwater pH 7.0
Lights are 10" from plants
temps go from 69(dark) to 81 w/ light on, 55% rh
I am running an old furnace blower motor for exhaust 4X10 into carbon filter, with (1)7" and (1)6" passive intakes.
The pH probe did not come today, but I used a metal probe one for soil and checked the pH of the soil, (around 5.5). I am not able to check the runoff pH until I get the new probe.
I did not know about the leaching. I have not been spraying the leaves until today because I thought I might have over did it with the neem.
Would the leaves burn from spraying the neem with the lights on? that would explain why it seems that the lower leaves that are not in direct light do not have the spotting.
How would I fix the leaching? with regular watering? I will not spray the leaves any more.
You can form a droplet on the leaf that acts as a magnifying glass, focusing the light and burning the area beneath. It's not common indoors, but it does happen.
Your pH reading on the rain water doesn't matter too much because rain water is REALLY REALLY 'soft'; it is not bad to use at all as long as you add the same dose of CalMag Plus that you would use on distilled or RO water. Check the pH AFTER you add nutrients with rain water, or any other water for that matter.
You are lucky- you have GH 3 part so you have a bottle of 'micro'. You can add about a tablespoon of that to your spray bottle and do light foliar feedings to restore color and lost nutrients to the upper leaves. A drop of dish soap helps it not make beads of water that can burn the leaf.

Will do. Is there a problem using water from a dehumidifier? What should be added differently than with tap water? (i have hard well water, 400ppm, that is softened with salt so I have been using the water from the dehumidifier, I get 2gal/day out of it.
That's the way to use your head for something other than a hat rack! :D
Just add CalMAg and treat it like any other source of distilled water.
If your water needs rise, or your air humidity drops and you can't get enough from the dehumidifier, you can take UNSOFTENED well water and cut it by 50% with dehumidifier water to yield a solution at 200ppm, assuming that the hardness is from primarily dissolved limestone.
Thanks for all your help on this Stinky.
Too bad it is all for nought. As the Kinks would say "I know what I am, I admit I'm a man and so is Lola".:cool:
So I yanked him and 8 of his clones and threw them in the bonfire last nite.:(:(:mad:
I still have 1 female and 7 clones from her trying to root now so I will continue with my log on them.
You can close this thread if you want, I probably won't be back.:D
I think your problem was that your ph was all messed up
You are right. My pH tester probe was bad. When I got the new one I did a flush and the water coming out was so low the plant got locked out.Quote:
