  1. Hey guys my plants are flowering now and are showing signs of heat stress but it's not possible the 400watt hps is at least 20" away from them I have a 80cfm intake and a 170cfm exhaust in a grow cabinet with a 1/8 " plexiglass sheild between the plants and the light I'm also having bad ph problems it's around 5.0 maybe lower and I have used lime and it won't correct ????? Is it maybe my water causing it idk they are in soil by the way.

    What're your temps?

    How can you be sure and us be sure it isn't heat if you don't state your temps?

    Edit: It definitely appears to be a lockout from a pH problem.

  4. When I click on your images the same one shows up multiple times. Could be an app issue.

  5. Your problem is clearly a pH issue. Getting that up will fix most of the problems and then you can go from there. What kind of water are you using?

  6. I can't seem to get the ph to level out in just using tap water should I use distilled ?? And my humidity hovers around 35% 40% at the highest I appreciate the help
     
  7. Yes use distilled until your runoff is around 5.5-6.0. That should help significantly. Your humidity is fine. Focus on that pH ASAP.
