    Yup I empty the bags right into tough totes filled with RO ph’d at 5.8 then scoop them with a strainer and shake them out. Ph is better now but still comes back a bit high. Thinking maybe submerging each pot at least partially? Do you Think that’s a option?

    Ya ou know I have always had some issue with it getting tired of it too lol. I’m thinking They might have had the beginning stages of root rot and that’s when they got sad. There was a lot of algae buildup on the top of the perlite, I have been trying to keep it under control but it was resilient so I cleaned the entire system top to bottom, which took me about six hours.

    Unfortunately perlite has such a low CEC level that your really not going to be able to change the PH of the perlite itself, but that low CEC level also means it won't hold nutrients or essentially anything (with proper irrigation) meaning you give it everything and you control the ph of the input water. As long as the nutrients are available at the time of feeding (ph of 5.6-6.4) then you'll be fine. Essentially your plants aren't even absorbing nutrients from your medium itself therefor it's ph will have minimal impact.

    Do you reuse your water after feeding or DTW? Could see this being a problem in a recirculating system but not drain to waste.

    It’s recirculating, night just switch back to hydroton after this run idk but the plants are looking very good but initially it was just half the room that drooped out while the others where just fine, then the droopy half picked up and the other half is starting to look like they are going to droop lol oddly enough it doesn’t seem like they have stopped growing but like they grow in spurts or sudden boosts.

    Are you noting the time of day of the droop? Some strains will droop at the end of lights on.

    I have been noticing little spots of undergrowth with some holes in them noticed a leaf kinda looked broken in half and out the center vein was a little wiggly worm, tiny, barley noticed it any idea how to get rid of bud worms? Hearing lights out and hit them with some pesticide.

    Bacillus Thurgenesis and Spinosad. Both available from Monterey brand nationwide.

    If they arent hiding in the pot alcohol and water worked wonders for spider mites. I can only assume they would work well here.

    5050 water and 90 iso alcohol will burn some of the leaf... 1to4 alchol/water doesnt .

    I hit mine with the 5050 first even though it stunts the plants for a few days i wanted those fucker gone lol then continued for 5 days straight to get any hatchlings

    Whats your ph ?

    I had the same thing happen when i go extremly acidic

    Awesome man thanks, I will try anything at this point. They are not too bad at this point from what I read at different stages, the larvae will eat differently only when the are nearing later growth do they eat the actual plant matter and thats only a few leaves here and there. I dug out the top layer of perlite and found quite a bit of dead little bugs, thinking fungus gnat larvae because I could only find them in the top.

    Mine did the same thing, I’m not 100% on exactly why but I believe it’s general dehydration. You may need to water a bit more, it could be salt buildup also causing the plant to not uptake any water. Too much nutes, salt buildup and, like coldsmoke said, ph. I would check ph first, do a large flush and then go back to nutes. My issue could have been the fungus gnats all along because that’s essentially what happens when not taken care of. Also would mention I think these lights bieing quite powerful accelerates symptoms more so than lower light conditions. I have been seeing plants reacting to water schedule ppm strengths much differently, like the margins for error is allot narrower.

    Nice build, I love seeing when someone does it right . I would love to have that much space, my next house will have more space for the ladies.
    I use the Sentinel controllers , I really like them. When I first got mine, I had it in the room, there is a lot of green lights that blink.
    Had one strain toss some nanners . I put it on a timer , fixed the problem.
    I now have blocked the light on the sensor and mounted the controller outside of the room, so I can monitor the room 24/7
    I did this do be able to give more CO2 .
    And have a fan outside the sealed room to pump in fresh air during lights out .

    I’m going to guess here.

    From the color of the main stock, when they where young, you up potted to soon, and watered to much n had a major Ca/Mg problem, and possibly have bugs in the soil.
    Had them doing better then hit them with a heavy feed and now they are locked out .
    I don’t think the curl is from light intensity because the lower leaves are curling 1st
    I can see a plant in the back ground the did a more normal burn (yellowing tips) this one salted up n locked out. Letting them dry out to much is bad too.

    I would calibrate your ph pen & ppm pen
    If you don’t have one , get them n the cal fluid,
    Then mix ph 6.5 RO water & flush
    Once you see run off , check ph & ppm
    If it’s running out at 5 , bring up the ph of the flush water to 7-7.5 , you want to bring down the ph run of to 6-6.5 and a low ppm
    Check for very small bugs in the run off.

    The last bit of water I run through the flush has a light dose of veg a&b n ca/mg n a root stimulus (25%ish dose)

    I do this because you just stripped the medium and they need something while they dry out.

    Been a hell of a night, was still trying to track down these issues with the plant and just seemed like I would never figure this issue out. Then to add insult to injury I was combing through the plants to try and find Anything, and happen to see that my main stocks are splitting pretty largely, Basically large cankers. I was freaking out a bit and went to reading and started to find out that this could be a fungal infection. But when I looked at the stocks again I noticed something odd, there where brown dimples that origanally Appeared as bark but at second glance they appeared to be more on the stock and higher up than yesterday. Long story short, they are armored mealybugs all my stocks. They have been sucking my plants of all the resources this is the only thing that I can think of at this time I don’t see any other bugs on them even during lights out. Here is some pics tell me what you guys think and if you have any experience with these pesky bugs advice would be greatly appreciated.
