    nah, whenever I see issues......I often see fox farms is all. I have no personal issue with them or Advanced. both are fine nutrients that do a swell job when used by me

    Hey bud. I just wanted to let you know that you were probably most accurate in your diagnosis. So thank you for your help. I def appreciate it. I checked my runoff. PH is perfect and in point. EC averaged 2.6-2.7 on most my plants. Pretty crazy for only 3 feedings. Upon discussing this issue with another friend and exploring possibilities, we decided to look into the effects of low RH. We believe that due to it being winter as well as the lights and heater running and drying everything out excessively, is that it's causing the plants to drink more water that nutes, spiking the ec ever so slightly. We believe this is overfert due to low RH. Raising it to 40% should fix the issue. That's for your help man. You were spot on!

    I never said anything about RH.
    If your runoff pH seems high (and it looks to be), it's because you've added fert to soil that already has fert.
    Water will evaporate out of soil when temp is high. This is why potted plants outdoors in hot weather need a lot of water.
    Don't assume that plants take up more water than nutrients. This might not be the case.

    yes you are
    "MEDIUM: promix hp mixed with ffof"

    ding ding ding,

    nutrient burn is nutrient burn. I never saw raising the humidity fix a pot of hot nutrients

    Runbho was referring to the additional nutes being used, not the soil brand.

    right I know, as you know that the Fox Farm soil brand contains fertilizers, enough to throw many growers here into to a similar frenzy aye?

    like, if my soil contained calcium, and I added more calcium for a calcium toxicity, I could not honestly state that I didnt use too much calcium because I dont use calcium(inaccurate, because it comes in my soil already right?)

    He DID state that he was using cal/mag with every watering.

    I'm beginning to believe maybe I'm not cut out for soil. My hydro plants have far less issues. So, apparently ec runoff in soil is meaningless and PH is the only thing you really check. You can't get an accurate reading checking ec of soil runoff. Any soil grower reading this can test this for themselves. I guarantee your runoff ec will be off the charts. I tested the runoff on my healthiest plants vs the least healthy and it was slightly higher on my healthier plant.

    In summary, my Tahoe ec runoff was 2.7ec and it was HUNGRY! It was NOT a deficiency. They are just really heavy feeders in flower. I gave a heavy watering 3 days after feeding 800ppm, and 3 days after the water, my plants started showing tell tale signs of potassium deficiency. I've started feeding more and things are slowly but surely getting better. Ugh. Soil is a pain in the ass but oh so good

    I suspected the super low humidity was drying the pots out faster. When that happens, the plants consumer water at an accelerated speed leaving unused salts left behind in the medium. Potentially causing salt build up and nute lock out. In my case, I was underfeeding. The reason my tahoes were struggling vs the others is because they're some seriously heavy feeders

    I'm sticking with promix from now on. Inert media is much easier to work with. As a complete noob, I get it. But, for me, prenuted soil became more difficult the more I learn.

    There was never any indication of "nutrient burn" either. That's why this issue was so frustrating to me. Just yellowing fan leaves. These girls grow so aggressively, they have high nute demands. I should've known better. They are the biggest plants in the garden maturing the fastest. It makes sense they'd have more requirements

    So it
    yeah that's what I was thinking honestly, but I'm a Hydro dude and never grown with soil so I didn't want to argue, but I have over fed and they get burned tips and the color is totally different I mean you can tell right off the bat you over fed. Anyways glad you figured it brother!

    Use the type that suits you best. But soil is actually easier, but the problem is that when you have too much fert in soil, you can't get it out. With hydro, to get out excess fert you just dump the water mix and start over.

    Thanks guys! Can't even tell you how much i appreciate everybody's help. I'm telling you I'd be lost without it. And to be honest, people disagree but I think staking my plants at week three might have damaged some roots and contributed.
    Anyway, just bought the Titan flo n gro 12 site ebb and flo style system. I prefer medicating with soil grown. But, I honestly really enjoy growing much more when doing hydro. I think I may switch my room to hydro for my patients and do a 6x6 soil grow for myself! Hope you all are having a good night!

    ill plants with a nutrient lockout would have strong run off too, as well as showing a deficiency for the lock out aye?
    this is one reason I begin my grow with the only ferts in the mix are the ones I put there, never a lock out, never a deficiency.
    I grow tahoe also, she doesnt feed heavily, at least not heavier than any other plant in the garden. You have to understand that just because a plant can handle strong nutrients, stronger than whats necessary for proper growth, does not mean she will show deficiencies when fed normally. It not about fiding out how high the ppms can be fed for best experience.

    I feed my tahoe plain water for 30 days of end flower with no issues in my soil, I hope your issues get fixed, could be a damaged/infected plant too, dont let that chase you from soil, it is the best!

    I dig it. Thanks bro. But, in order for lock out to occur, doesn't ph have to be off? Isn't it the ph being out of range that prevents nutrients from being used by the plant? That's what's weird. My PH is in point. My Tahoe is unfortunately not the clone only. They're from seed by Cali connection. The only reason I even determined it was a heavy feeder was due to it showing deficiencies. The only reason I even know it can handle a stronger nutrients is because she's unhappy and showing deficiencies if I don't. So in essence, if she wasn't sick and showing deficiencies i wouldn't even know it could handle stronger nutes. I think I'll be happier with proven genetics rather than seeds. So much unstable shit out there.

    30 days without food is crazy. I went 9 days without feeding my glue cross and I'm already getting purpling on the leaves showing a pretty heavy phosphorous deficiency. Maybe I have really heavy feeders or my lighting is just super intense.
    Oh, and my glue cross became deficient merely by giving a mildly heavy watering after a feeding. Literally I fed 850ppm, 3 days later water only, and 3 days later I have deficiencies. AND, when I watered and checked the run off it was nearly 3.0ec. Which is why I ran a little extra water through it and brought the run off ec down a bit. The point is trying to make is runoff ec is meaningless. According to my runoff my plant was overfed (or so I figured) but it wasn't. It was hungry. I've seen YouTube videos of soil growers getting 4.0+ ec from their runoff. Leaves me wondering what ec runoff equates to a plant being properly fed. Because in my case, 2.7ec runoff equaled a hungry, deficient plant.

    I grow organic, in dirt, 30 days without additives is normal considering my soil build, experience. a couple days of water only in my hydro and losses occur I agree.
    And far out to the seed form tahoe, thats maybe my most memorable , the longest stay in the garden actually, then medicine man, both still are stars

    Thanks bud. I don't think I can ever give up soil, but anything more than a few plants becomes quite a chore. I don't know what to think regarding this Tahoe. One thing for sure is that all 3 pheno's are fantastic but #1 and #2 are ridiculous. Whatever was going on didn't affect quality by any means :)
    Ive always wanted to do a 100% organic run. Like super soil or something. I've always been curious to know just how much better it really is in a side by side test. Sounds like my next experiment. Would have to be super soil though cause I wouldn't want to have to mix separate nutes for that one plant.
    And shout out to whoever it is thsts breeding genetics at Cali connection and to whoever created the Tahoe. I don't have too too much experience with seeds, but out of 15-16 different genetics from multiple breeders, this is prob in the top 2. Crazy impressive. Nice work whoever you are. Very well done.

    Potassium: Leaves have a papery appearance; dead areas along the edges of leaves; growth is stunted...

    Magnesium: Lower leaves turn yellow along the tips and margin and between the veins; the lower leaves wilt...

    Calcium: Young stems and new leaves die...

    Zinc: Leaf tissue between the veins is lighter in color; yellowed; papery in appearance...

    Iron: Leaf tissue appears yellow, while the veins remain green...

    Copper: Leaf edges appear dark green or blue; leaf edges curl upward; young leaves permanently wilt...

    Sulfur: Young leaves turn pale green, while the older leaves remain green; plant is stunted and spindly...

    Mananese: Growth is stunted; lower leaves have a checkered pattern of yellow and green...

    Molybdenum: Leaves are stunted, pale green, and malformed...
