What causes these dead tips?

    Is this from nutrient burn? I don’t use fertilizer, only URB and Organic Super Soil mix with Fox Farms Organics. I’m guessing this occurred because of fresh nutrients during transplant?

    Too hot as in PH or temperature in the grow environment is too hot?

    That means it has too much nitrogen in the soil.

    I just noticed one of my plants has the same starting and just wondering to try flush it now or just wait till next watering day and water till theres decent run off

    If you're reasonably sure this is what's going on, then the longer you wait the worse I imagine the damage will be.

    Flush, measure run off, get PPM's to around 350 and PH to 6.5

    Wouldn’t my TDS ppm be determined by the water I’m using to flush?

    Agreed, being my very first grow, I did make the mistake early on of unnecessarily top feeding castings and causing one plant nutrient burn.

    I scrapped the top layer of soil off and flushed, that stopped the burn progression. The plant slowed in growth but recovered.

    In this case, the tips burnt and the progression stopped. It is now day three and the burn never got worse. I didn’t flush.

    This is an organic grow and I’m only using the super soil and URB for watering. I’m not feeding any fertilizer.

    I now realize that didn’t mix the super soil correctly and the roots made contact with the richer soil (which should have only been in the bottom 1/3). So they got a little surge of nutrients, but quickly adjusted.

    Heat: 77
    Light: 18/6 true 2000w (Spider Farmer) at 24” away
    Humidity: 55 Rh
    Ph: In 6.5 Out 6.2
    CO2: 700-900ppm day 500ppm night

    Yes. If you use RO like I do, I just add 12 points to the total.
    If you are using tap, then measure it and add nutes to make the total PPM's.
    Oh if you are adding PH'ed water at 6.5 and run off is 6.2, adjust your water to PH of say 6.8 and see if the run off is closer to your target of 6.5

    It doesn't have to be complicated.

    I know it doesn’t. But this is a 100% organic grow, plus I’m meticulous, so I make it a little more difficult haha

    But yes, great grow!

    Ya i guess i probably shouldn’t classify it as difficult haha. Everything is just new as this is my first ever grow. Its a lot of initial learning, but i’m feeling much more confident now.

    Obviously they are hardy “weeds.”
