Spots on leaves and don't know what they are? + pics

[Freda Felcher]

So far everything has been going well with my outdoor grow, but today I noticed some spots showing up on my plants. I'm doing some research and the only thing it looks close to that i have found is calcium or magnesium def. Thanks for any help you can provide + reps!

I looked all over the plant and umder the leaves but didnt see anything. I was going to bring a leaf home and put it under the microscope but I don't want to contaminate my indoor grow if it is a pest..

I have a couple plants that look like yours, just not as bad and started a thread earlier today and somebody said it was a pest. I went to home depot and got some pest killer and sprayed them with that. I hope it takes care of the problem. I didn't see any pests either.

Were they specific on what type of pest? I have neem oil and spinosad bug killer but I would like to know what it is specifically before I start spraying.

Here's the link to my thread. Good luck bro and keep this thread updated.

have you checked ph? you are experiencing ph spotting, so your ph is definitely off. when this happens, certain nutrients are locked out, creating deficiencies and headaches galore. what water are you using? what nutes? it really doesnt look like bugs, bugs such as thrips and spider mites leave MUCH smaller and usually many more marks on leaves than what you have.

I'm using water from a nearby creek and for my tea so far i use Mexican Guano, Jamaican guano, sea kelp, mollases, worm castings and some liquid karma. I also top dress with guano and casting's from time to time if we get a lot of rain.

Goddamn bugs.

I always wondered wtf those spots were, always thought they were snails or some sort of pest. I Never would have guessed it was a pH problem. I have a decent garden in front of my house with some good sized sunflowers, which seem to get bombed by these spots, particularly on the bottom leaves. The soil is nicely prepared too, as we've added plenty of compost throughout the years and also compost tea, but never once checked the pH. For pests you can pretty much use anything to get rid of them. I've tried both garlic and soap in water and it seems to work fine, I only had problems with spider mites last year but i'm guessing it would handle this problem as well

I'd hit it with diluted neem oil. It isn't going to do anything bad. Neem oil targets insects that attack the leaves, and doesn't harm insects like spiders, that are beneficial. (Unless you hit them during your spraying)

You may not see immediate effects, like you would with other non organic pesticides. It inhibits their life cycle, some insects even forget to eat. The problem is, it degrades somewhat quickly and you have to keep up on it. Remember to spray the undersides of the leaves if you decide to use the Neem Oil.

this is a great tea! i live in a city so a nearby creek would be cause for concern for me as far as possible pollutants... i realize this might not be the case for you though. i would definitely test the ph of the creek water by itself either way just to be sure. there could be some deposits of something upstream that your plants arent too stoked on? idk just throwin out possibilities because im 99.9% sure that isnt bug damage

if it is bug damage though, my money is on leafhoppers. if i were you id spray it with neem oil as well... make sure to cover all possibilities and then youll for sure fix the issue!

I have them growing in a backwoods farmland area, so runoff from various chemicals like pestices, herbicides and fertilizers are a possibility. I don't know why i hav'nt done this before, but I'm going to bring my Ph tester along today and see what i can find out from my water source. The neem oil sounds like a good idea as well, it can't hurt, right?
If i do find the ph is off, should i immediately start flushing with balanced water? i can bring along my ph up and down along as well...

if the ph is off, id seriously worry about what might be getting into the creek upstream from you... like to the point where i wouldnt just adjust it with ph up/down because of what could be in it. maybe roll up a fatty and take a walk upstream to check it out? depending on who might be up there this might not be a great idea though... neem can clog the stomata on the leaves, so make sure to use a diluted solution in water with drop or 2 of dish soap as an emulsifier. oh and ya... if you find the ph is off try to flush it with water you already know is clean and in the correct ph range.

good luck and give an update once youve checked it out!

 

[vallilynn]

plz dont use any insecticde that is harmful to people, the plants will asorb it then you smoke i you smoke the chemicals, use neem. be careful what you put on them
good luck

I checked my plants after the rain this evening and they look a little worse with more leaf damage. I have decided through other threads this may be spider mites. I'm going to hit them with neem or possibly use some Monterey Garden Organic Insect Spray with spinosad. Can anyone tell me if this stuff would work? The plants are still in veg so I'm not worried about the product buds getting residue..
I also ran a pH test and found the creek water to be at 7.8. High but not horrible. Any other suggestions guys and gals?

 

[Comando]

7.8 is WAAAAYY to high...you need to down in between 6.0 and 6.5 Like your tea...did you copy that from the Blueberry Kush Organic grow....???? similar...lets see some more pics....
