Help! I am finding spots on my leaves and can't identify.

Hello, I am finding leaves with spots on them and they seem to be spreading. I am starting to see the same spots on other plants also.
I have been searching the forum and the only thread that I found had not been answered. I am using complete Canna Terra line of nutes,
and using sunshine advanced mix #4.watering/feeding with a ph of around5.8 -6.2. Any info would be deeply appreciated! Thank You!

I've always blamed it on nute splash so curious to see what others say.

Had that same issue recently. Mine went away gave mine a 1/4 shot of some organic tea. Mine I think was from putting in new soil and missing something.

I am having the same issue should I flush my soil and re add the nutrients? I read the its 3 gallons for every gallon of soil. Would it harm my plant if I where to flush my soil? Like giving to much water or something like that?

experiencing this as well

What does sunshine mix#4 contain?

Isn't it mainly coco based with perlite?

If so what you are seeing is most probably caused by a lack of magnesium.

What stage is your plant in, you are not very specific with your post and to get a good idea of what is going on you will need to include more details about your grow (hydro or soil, flowering or veg, etc....). When are you testing PH(after nutes are added to water or before)? Looking at the leaf in the picture I would say your PH is acidic, and if you are using soil you should be staying around 6.5 PH, even 5.8 can burn plants in soil, 6.5 allows all nutrients to be absorbed by the roots at a maximum rate. What are you using to test your PH? Come back with some more details and I might be able to give you some more help with your problem, but for now I would try to test your PH(after adding your nutes) with a PH meter other than your own, and if you are using liquid PH tester you need to stop and buy a quality meter like Blue Labs, it makes a world of difference.

One more thing I noticed, it looks like your plant has stunted growth, which is another sign of a PH problem.

ph at 5.5 and add epson salts

No prob flushing just let it get thirsty again before food/water

Yes!

Epsom salt. 1 tsp-1 TBS per gallon of water.

Up that pH! Even "soilless" needs to be near 6.5 for most strains.
