    Having an issue on first run with coco

    Trying out coco for the first time under an HLG 300L, feeding GH trio + calmag every few days at a pH of 6. I haven’t seen this before when doing DWC. Thoughts?

    Holy mother of... Don't worry about it. It's a happy little mutation that freaks people out. Looks cool but can be bothersome. Double check the undersides of the leaves with a loupe or other convenient magnification implements for bugs, just to make sure.
    I can't tell you what it is, but I can tell you I get it enough that I don't worry about it. Also in coco, different nutrients. Me, personally, I use calmag if I use nutrients.
    Otherwise, it looks real healthy.
    Auto or fem?

      Haha tyvm, that’s good to hear. I was thinking bugs too so I kept checking under the leaves expecting to find squatters but everything was clean and clear.

      yeah, I have a few auto Girl Scout Cookies running right now. Usually do more than one strain but wanted to keep things simple for the first run with coco.

        Your pH is a little high. I target 5.8 in my coco grow. Don't skimp on the cal mag.
        Don't worry, be happy, grow sticky buds.

          Same here. 5.8-5.9 during veg. 6.0-6.1 first few weeks of flower then 6.2-6.4 to finish with super frosty tops.

        bboyfromwayback After much penitent introspection and acquiescing to the great wisdom of my peers, I have recently settled on 6.0 for flowering my autos. You lost me with the 6.2-6.4 finish. Do you have a time before harvest for finish? You also do autos?

        Wish that I was on ol' frosty top,
        down in the Tennessee hills.
        Got good smoke upon ol' frosty top,
        God, I hate climbing hills.
        Frosty top, you'll always be,
        grown at home for me.
        Good ol' frosty top,
        got me on my knees.

        C'mon, mule!

          Once they stop developing new growth I let the ph go a little higher which is usually around week 5 of flower. I do grow autos occasionally and had great success with the last few by growing them exactly like a regular plant. The last two were off the same reservoir as my photos

          To the tune of Rocky Top....hmmm. What's the next verse?

        Always vary your pH.

        In coco I do like 5.8 to 6.2 and a bit in veg then around 6.1 to 6.3 in flower but a few outside that range also, bit lower, bit higher. I try and read the plants as best I can and sort of move the average to where I think she needs it.

        It seems to mostly keep them pretty happy.

        That pigment issue should go away as she matures but it could be pests or a virus....but I think you should be fine

          Coco is hydro so it should be wet all the time, I feed water a couple of times a day with an autofeed setup or ebb & flow. I also keep my PH above 6.0 unless the plant tells me it wants it lower. If your taking good care of your roots I dont think PH is nearly as critica. Just my opinion though

            pH absolutely critical. Fertigation frequency maybe a bit less so but your right there re hydro. A high frequency without drowning them seems to produce the best yields. You can over do it in coco with too much and fungus gnats and algal growth on top is a fraction too much in most cases, although I have had one plant where it wasn't as happy when I dropped back the frequency to get rid of the green on top of the coco.

            Where talking a pretty big plant in a pretty small pot though. It's all relative.

            I did some experimenting and keeping the Sap PH if at 6.4 and the brink above 12 I let the feed PH drift from 5.7 to 6.7 and the plants didnt seem to care. That was in a RDWC system, I havnt tried it in coco yet but I wold bet it will be the same

          Once two growers popped some frosty top
          hopin' for a deep green field.
          Growers done come back with frosty top
          guessin' 'bout a two-ton yield.
          Green corn's what they call ol' frosty top
          can't see be seen from a car.
          That's why all the folks smoke frosty top
          and buy their weed in a jar.
