    Anyone here ever find that overfeeding PPM shows up as lock-out/deficiencies or excess symptoms?

    For the first time in a while I am going to try and give my Plants exactly the amount they consume of nutrients and no more! in Flowering. This is what I try and do in Veg but for some reason since they drop their nutrient drawn down by over 30% after the flip, I have a hard time going that...

    How concentrated to make Nutrient Solution in my 13 Gallon RDWC Reservoir for One big Plant?

    I am modifying my Power Grower RDWC systems to have a 13 Gallon Reservoir. And in general my tendency has been to make my PPM stronger then what they actually consume nutrient wise! I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir...

    Unexplained Mild Potassium Deficiency after the flip

    WOW that is some INFO! Crazy because you just addressed a thought (question I was pondering) I had which was could a build up of calcium during veg actually effect the trasition to bloom -- even though there are plenty of available K nutrients after the flip? Meaning the problem actually...

    Unexplained Mild Potassium Deficiency after the flip

    Thank you as well, I hoped this level of mild K deficiency would not overly impact the yield, adn as i mentioned. IT primarily affect leaves that get defoliated with this crazy Strain Golosa by Delicious Seeds. Not to hijack my own thread but this strain finally taught me the significance of...

    Unexplained Mild Potassium Deficiency after the flip

    Thank you very much this is what I actually meant to focus on. Can simply running too high an E.C actually create the condition for Potassium Lockout? I also read contrary to my simple logic that higher powered LEDs make the plants drink more water which almost suggests that they might prefer...

    Unexplained Mild Potassium Deficiency after the flip

    Another thought I had is I wondered if my Dehumidifer could cause Potassium Symptoms drying out the air too much?

    Unexplained Mild Potassium Deficiency after the flip

    I don't ever remember having this for years I have grown larger plants in my slightly undersized GH power Grower RDWC's.Recently IT was clearly aggravated by a Calcium boost in late veg as I seemed to be having a Cal deficiency in veg as my plants got bigger. However I stopped boosting...

    DWC bubbles question

    So can you confirm is that level of turbulence 'not' too much for the roots causing breaking roots? I just got a 20 Watt pump with a 4 manifold for my 13 gallon Single RDWC units. With three small air stones (one for the top drip) I get that rising turbulent spots where the air stone is. I am...

    How many bubbles for a DWC?

    MaJor Breakthrough I just stretched the Soaker Hose and getting like three times of more the air flow maybe 5X. The surface break and droplets have to more than make up for lots of small bubbles? Not to mention I have exposed roots between inner bucket (net pot equivalent) and water level. I am...

    Max PPF/PPFD with and without Co2

    I do not see signs of light stress there! 800-1200 I guess that means your highest tops are topping out at 1200 PPFD? That is helpfull

    Max PPF/PPFD with and without Co2

    I am struggling to figure out the ideal hanging height of my Scorpion Diablo. Originally when I got it I was confused then I got Photone Par Light Meter for Iphone. At this time I decided since the measurement was identical to my 315 CMH at 15 inches, that that would be fine. However I only...

    Max PPF/PPFD with and without Co2

    When it says 510 Minimum, does that mean at the top, at the middle, bottom etc>?? This is the part I am confused by. I suppose the highest point of the plant (assuming not perfectly lst'd) should be no more than 1000 to avoid LED burn? Or could the highest point handle 1500, if it was only 2 or...

    Bizarre stunted MAC1, 15% the size of a Tropicana Cherry acquired at the same time after 6 weeks?

    I got these 2 clones from the CC clone supplier out of California... They came in small cubes with small roots and were immediately transplanted into my new super blast off 50/50 Coco/Perlite mix in 5-6 inch pots... I am experimenting using this as a secondary Clone incubation medium before...

    Advice & Help Needed!! "Purple Stems" (Clones)

    After experimenting running Coco "veg" nutes at 1 ml per liter as per AN Sensi Coco instructions, I have decided that Coco Veg Nutes, and Veg nute are not recommended for a reason. Plants need more phosphorus during rooting if anything. Some root with no nutrients but anyway; I believe the...

    Please help lighting intensity?

    I have a HLG Scorpion Diablo running with no co2. Originally when I checked PAR against my 315 CMH's I discovered they measure the same at 15 inches so I figured why shouldn't they be able to handle the same distance as my CMH? Took me this long to discover another form of measurement that has...

    General hydroponics nutes, what's your ppm at during flower?

    Who made that chart. I modified my Reservoir to much bigger and I think I should be using a lower concentration now. I have a 13 Gallon reservoir for plants that drink 2 gallons per day RDWC. What do you recommend...

    YELLOW veins

    I forgot to mention after switching to the larger reservoir my PH has been so good I can not even believe it. It went from going up instantly to gradually going down (high e.c.). The instant up PH to 7+ I believe was a microbe I may have been dealing with and another story all together..
