What's this white stuff?

  1. Just like the topic says, what is it? It is only on some leaves on all 3 plants. It's only on one side of all 3 plants. I had moved and twisted the plans before I realized that so I don't know if it was all on the North side, East Side, ect . It doesn't brush off with a dry finger but a wetted finger can wipe it off.

    Is it just pollen of some sort? Mold? 20190804_152038.jpg 20190804_161557.jpg 20190804_161611.jpg 20190804_161638.jpg 20190804_161646.jpg

  3. Powdery Mildew odds are. Green Cure once a week every week.
    Baking soda will work in a pinch. 1 tablespoon per gallon of water. Drench spray.

    Most hydroponic shops will have it.

    Caterpillars are your next big threat. BT is the fix for them.

  4. Even tho it's on a minor percentage of leaves? Intermixed with perfectly green ones? And only on one side of the plants?

  5. Yeah bro, powdery midlew forsure imo.
     
  6. I took a closer look and decided to trim the offending leaves off and go from there. I noticed as I was trimming that it was just sugar leaves that looked like this. No other leaves that I found had this stuff on them.

  7. That's not a sugar leaf in your hand there...
     
  8. Seems to ME that is about as un-pragmatic as you can get.

  9. Maybe im confusing lingo. The leaves that are off the bottom of each "grouping" that have no hairs/ nodules/ whatever between them. I'll grab a pic here in a few to clarify.
