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 ?
 
it had built up to 8.1......and is now safely down at 6.1......I didnt realize but one of my supplements was makin my water alkaline.
 
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.
 
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.
