  • Yellow centers.

    Strange sequence o events last night.

    I grow autos under platinum p900 lights. The ladies are about 30 days old

    Last night

    I added the Bloom light about 16 hours ago,

    I lipped a breaker and lights were out for around 12 hours

    And, i turned the CO2 rom 800 ppm to 1400

    I woke up and all my plants had the bright yellow centers, I read the symptoms here could be iron deficient. I dont think thats the issue, i water at around 6.5 and all the plants not just theese 4 have same issues.

    They were so happy and healthy beforre change of events.

    Hi Player, Certainly an iron deficiency isn't going to suddenly appear overnight on a bunch of plants. I'm a hydro grower, so I have no expertise in your issues, but I would still suggest returning all conditions EXCEPT for the light to the way they were before. Maybe you went up on the CO2 too fast? Is that possible?

        How close is your light? Maybe early stage light burn? You said you added the bloom light - is it a lot brighter/closer to the plant tops? Just a thought. Good luck!
