What Nutrient's are you using?dry amendments to the soil are:3/4 cup blood meal,3/4 cup bone meal,1/2 cup alphaphal meal,3/4 cup kelp meal,1 cup ewc,3/4 cup dolomite lime
What method of pH test was administered? Using Strips? pH pen?liquid drops
How often are you watering?every 3 to 4 days veg 2 to 3 days flower
When was your last feeding and how often are you feeding?

Is your water HARD or SOFT?
What water are you using? Reverse Osmosis (RO)? Tap? Bottled?tap water that i let sit out for 24 to 48 hours before i use it

I was thinking it might be a calcium def. and have treated with a foliar spray of dolomite lime,1 teaspoon per quart,and have watered 1 teaspoon dolomite lime per gallon.Foliar fed veg and mom only not flowering plant.Watered both veg and flowering plants.Any suggestions? I have to water later today and would like to know what i need to do.This is the first time i have used this mix with the alphalpha meal and ewc.I have used it before with no problems minus those two ingredients.Just was trying to give them another source of N because of early yellowing.I don`t think its that because my mom is showing the same symptoms and is in FFOF soil and i use FF nutes for her.let me know if you need any more info to help.Thanks

PS.how in the hell to i attach the photo!

You got powdery mildew for one....

 

[TokerJones]

The white stuff on the leaves is the residue from the dolomite lime foliar spray.

 

[HeadyPete]

I see that on some, but that last pic looks a lot like PM. If it is just residue, my apologies and Yay!

Can you put up some pix of the whole plants?

 

[TokerJones]

I thought the same thing a day after i spryed..lol..Not sure what esle to try, any other ideas Heady and thanks for you response!

 

[Mr.Hades]

It looks kind of like spidermites at first but then I saw the other pics... Post pics of the undersides of the leaves if you can?

 

[TokerJones]

Here you go,not the best but i hope it`ll do.Let me know if you need another.

 

[hempluvr]

TokerJones you should have added that dolomite lime to the medium and not in spray form. That does look exactly like powdery mildew. The lime is ment for ph stability. With it in your medium you should not have to spray them with anything. Anything that makes your plants look like that cannot be a good thing. I would flush them asap,check your ph in the runoff and go from there. Make sure that is not powdery mildew,sure looks like it. Leaves with over 50% damage remove. Good luck to you and hope I was able to help,Keep It GreeN!

 

[TokerJones]

Thanks,I thought it might have been a calcium def. as i compared pics in the sticky,http://www.icmag.com/ic/showthread.php?t=11688.Thats is why I used dolomite lime as a foliar spray for the clacium. I did add it to my soil,3/4 cup to the mix I use.I also added it to a watering at 1 teaspoon per gallon, as it says in the sticky for calcium def. I am organic and all my amendments are in the soil so flushing kinda was my last resort.Can you look at the link and let me know what you think by comparing pictures?Also,what causes powdery mildew?Thanks

 

[TokerJones]

Ok,took some more pics. Alot better than the others.Some are of the plants in veg and some are in flower.Please let me know if you guys/gals still think its powdery mildew.I foliar sprayed my plants with just ph`d water to rinse the dolomite lime off.It looks alot different.

First two pics are the plants in flower.
The second two pics are of the same plant in veg.Its the worst one.The rest seem to be fine.

Any ideas??

 

[Mr.Hades]

Yeah, it doesnt look like powdery mildew but definately looks similar to spider mite damage but not entirely... Have you checked for pests?

 

[TokerJones]

Yeah I was pretty sure it wasn`t the powdery mildew,but i do agree it did look like it.

I check for pests on the regular.Had the mites one time and since then bug duty is high on the list.

 

[Mr. Hugeblunts]

Could it be Magnesium deficiency? I believe that has a similar appearance to mites and leads to those spots.

 

[bitpoop21]

I would flush your soil good with ph adjusted water and 25% nutrients.

 

[TokerJones]

Could it be Magnesium deficiency? I believe that has a similar appearance to mites and leads to those spots.

I routinely add epsom salts to my water schedule because off a def. in the past.

Im thinking it might be ph.I checked my water yesterday before i watered it look a bit on the high side,7.5-8 range.i will adjust and see how it goes.

 

[HeadyPete]

Is this getting worse or staying the same?

You ph should be at 6.3 and this will definitely cause problems like yours due to nutrient lockout. It looks like calcium, but usually there is adequate calcium in tap water. So this leads me to believe high ph is the culprit. Lime breaks down slowly and will also raise up the ph of the mix. If the ph is out, it doesn't matter what you add, it wil be unavailable to the plants and will become toxic to them.

If you are using FF or ProMix or some mix that already has lime in it, you shouldn't add more. Although it does add cal and mag, it raises ph too much. Use molasses, cal mag, epsom etc for your cal and/or mag needs

The only time to use it is if you are making your own peat based mix, peat being acidic and needing the lime to raise ph to where the plants like it (6.3ish).

So slowly begin lowering the ph of your water over days and many waterings until it is down in the 6.3 area, and your soil will come down as well.

Good luck

Heady, thanks for the input! I agree with you,i think its ph.i adjusted the water last watrering and did ad some molasses.things seem to have slowed down in veg.Haven`t checked my flower room yet(lights aren`t on yet).Thats pretty much what I am going to do,get the ph straight and go from there.Thanks for your help!I let everyone know how things work out.
