  5. That's true if you don't have good air circulation but plants do still flower successfully outside when it rains ;)
  6. firsttimer0927 I have the same problem I'm in the 4th week of flowering most say it's suppose to do that because the flowers are pulling energy to flower are you getting new growth if so I wouldn't worry.It also can be a defiency what I did was add some epson salt 1/2 tsp. to a half gal of water it seem to help but I've had yellowing after the second week but I notice that with the energy being pulled to the flowers there getting more densier and it's not a whole lot maybe 1 per stem I just pull them so I have less to trim at the end.hope this helps
  7. What hightime said. It's nitrogen theft, but it happens. Buds want what the leaves have. Let it happen.
  8. Normal process. Google it, u will see.
  9. I Thought that plants needed less nitrogen during flowering and more potassium. Higher levels of nitrogen are needed during veg state. So it doesn't seem like nitrogen is the problem. correct me if I'm wrong.

    nitrogen is no longer used from the soil. Or used less. So it stops taking nitrogen from the soil and gets it from it's leafs. This process turning your leafs yellow a few at a time. This is why you use a lower fert first number like 0-10-10. You do not need nitrogen is your ferts for the plant stopped using it in the soil.

    Brown spots I not sure.

    The pic above is days old. Can you post another pic of your plant now 2 days later?

    Your plants look fine. I would like to see a little darker green though. Or perhaps it's the camera. Mine does that as well. Night time pics show true color or close to. Or darker anyway..

  11. Im high guy, But i think you need some magical, or cal-mag. it will help with that heat and burn leaf problem.
