    Question rust spots on leaves?

    Just like the title says, "rust spots on leaves".....why does this happen. I've never experienced this on my plants before. But some new mothers I started(blue skunk) have rusty coloured spots on the lower leaves....Does anyone know what is causing this ?

    I keep mine at 6.2 to 6.3.

    When do you check your ph, right after or an hour after, you add your nutes.

    I have a PH pen so its easy for me to check...the batts were dead though, thats why I had my issue. To answer your question ganjaguru.....I let my res sit for 24 hrs before I add my nutes, it helps evaporate some of the stuff in the water like chlorine. I check my PH after I add my nutes, and right before I feed my ladies.

    I recommend using reverse osmosis. So you don't have to wait 24 hours.

    yeah, thats still an extra expense and not 1 that I consider a necessity. I'm patient lol ...Besides my water here is good 100-130 ppm, and thats before I let it sit.
