Hey WP

So was at hydro store yesterday to get some more soil, and was gonna buy some GH nutes, to give them a try.  The owner told me to stay with Fox Farms, he said better quality and flavor.  That's when I told him about my problem with my weed not smelling or having that real nice flavor, it's fire, and fucks you up, and it don't taste bad but not that you guys know what i'm saying that taste.  So we started talking temps first, he came right out and said I have a ph problem and asked me what kind of run off i had, and i said I know my run off is acidic, he was emphatic that that was the problem.  Then he brought me over to the all so common ph and nutrient absorbtion chart and he mentioned how if the soil is acidic, it won't get no sulfur which aids in the ripening of the fruit/buds.  And i told him about my one Headband that literally it is in week 14 of flower, and still pushing pistils.  So does any of this sound like it could hold water?  any truth to it in your opinions.  And I know either SHB or SBL, the dude that lives in TX, that has the hot ass weather also, is having these same issues with the smell thing.  Do any of you guys top dress with Lime? to keep ph in check? Btw the ph coming out the bottom is 5 and i'm pooring 7 from the top.   Thanks for responding.  Peace.

    Hey China, does make sense, but in my opinion testing the runoff is less accurate that testing the soil. From what I read when you PH your runoff you subtract 1.0and that's your actual runoff. I think it would be better if you put a little soil in the tube and add water shake and see what color you get. I think the heat thing is more your issue than PH or it would not still be throwing out pistols, and you would have more symptoms. Just my thought I'm curious what the rest think.

      thanx hulk, well i'm addressing the heat issue, now i'm gonna tackle my soil ph issue and see if I get some stink going on. This may turn out to be a perfect case of be careful for what you wish for, I don't even turn on a carbon filter atm LOL.

    I'm confused.

    How can the runoff be anything BUT acidic?

    Nobody I know waters at or above ph 7.0. So the water is acidic going in.

    In order for the soil to raise the ph, wouldn't it have to be caustic?

     I'm with Hulk, do a slurry test on your soil, and see where you're actually at, where it matters.

     Then check into your temps. If it's a ph problem, the leaves would tell you, not the smell.

      Run off is not a good indicator of PH . Like Rbt said, do a slurry or a saturate test 50/50. You don't have to filter it either.

    Honestly I dont know how weed can be good smoke and not smell since the two kind of go hand in hand. Can you go to a dispensary and smell their buds to make sure the problem isn’t your nose?

    I don’t have much faith in testing runoff but it seems like it should be same PH coming and going. I have read that if the PH of the runoff is low below 5.0 you have a salt build up going on but other things will tell you that too. Healthy & pretty plants don’t have salt problems.

    Seems like your in going PH would have to be way off before the PH would lock out sulfur so maybe you need a little more sulfur, most bloom boosters and potassium additives have some sulfur in there.

    If you think it may be the soil being to acidic why not try coco coir?

      I used a K mix that was 18% sulfur and it worked great for boosting the buds but the wife complained it smelled like rotten eggs and once something is in her head its trapped for eternity.

      Yep, hydro and soil are a lot alike except for the bugs, slow growth, smaller yields, obstructed roots, etc. Other than that you can grow plants in either. LOL.

    You have a couple different probs. Your Hydro dude knows what he's talkin about . Your PH is important for nutrient absorbtion. If it's 7.0 goin in and 5.0 comin out, that means your substrate PH is REALLY LOW... like in the 4's . You should be havin all kinds of probs ! This will certainly fuck up the process and affect the taste and smell. You can topdress with lime, dolomitic lime, or even gypsum . Also, get a bloom booster that cantains Potassium sulfate, if it's not to late. The high temps aren't gunna hurt you unless they get above 85 degrees, with no air movement. Is this indoors or out ? Heat can be a critical factor indoors. Outdoors it's a totally different situation. Weed loves hot, sunny weather ! BTW... how did you media get so acidic ?

    I don’t believe it. I’m going with temp. I use GH nutrients at the 6.3-6.7 Ph and I have no problem with my finished product smelling very loud and tasting great. You can tell the different strains apart by smelling or tasting them. I think temps has been your problem myself. Good luck and happy growing my friend!!

      My runoff comes out at 6.5 every watering. I put it in the top at 6.3 one time, 6.7 the next, and back to 6.3 the next. I fluctuate every watering. That is in FFOF with 25% extra perlite. I never feed at full strength either!

      Flood that bitch with 1tsp. Recharge per gallon of water and have a lot of runoff and look at her in a couple hours! I would almost bet that will fix your problem! You will then have to back off your feedings if you have a hot room.

    I don't know if this is true or not, but i use GH flora base nutes and have plenty of good smell and taste with my weed. My weed does not grow in temps any hotter than 85*F, and this is with the lights on. I am not a scientist or a botanist, so i don't know all the proper terms, etc., but i know what works for me. I really think this guy wants you to stick with the nutes you are using and not switch up. If i was you i would do what i wanted.  Peace

    To SS   The low run off PH can mean a couple of things. Leaves lookin like shit is caused by micro nutrient toxicity (iron,manganese,zinc), due to an acidic substrate. The substrate could also be depleted of it's buffering capacity (bi-carbonates) from continuous irrigation. Salt build up can cause a low PH, and it can be a factor, but it isn't the main, or only factor. TBS...I'm not sure what week of flower he's at but a flush would be beneficial for both neutralizing PH and removing excess nutes.

      You're right Bill, but this far into flower I'm hoping for his sake it's not a N toxicity. The "claw" is what separates N from a Fe toxicity. With his PH being really low it's pointing more towards a Fe toxicity due to it's high absorption rate....  more

      The only way to get a toxicity of a micronutrient is by feeding too heavy with the FloraMicro or a Ph problem. Your not exceeding 4ml FloraMicro per gallon of water are you? I have never had a toxicity of any kind at that level and that is full strength. ...  more
