  • Wifi: is this nutrient burn?

    Posted by GroBunny on December 29, 2020 at 3:32 pm

    New to this strain.

    Do these spots look familiar?

    I’m thinking I overfed bloom nutrients. I’m going to flush and measure the runoff tomorrow, but it’s wifi so other people here probably have experience with it.

    Could also be purpling or light burn due to being too close to the light while having too low night temps. 26 degrees during the day. 18 degrees at night so enough to cause it. I raised the light a bit and turned the heat in the room too.

    Got any idea what this is?

    I’m having the exact same problem with this strain.

    It’s difficult to remedy.

      It was nutrient burn for me. I had to flush and use quite a bit of water to solve it. Just measure the runoff and make sure you correct the PH and get the EC way down too. I just brought down the EC to 1.4 and then fed water one more time the next feeding till runoff because I’m cheap about wasting nutes, but you’d probably be better off flushing until the EC is like 0.7 and then feeding the next time at half the strength you fed the time before. That’s how you’re supposed to do it anyhow. I’m in the 3rd week of flower though so I don’t want to risk deficiencies during such a critical bud growth stage.
