Yep, back in 1828 growers realized this, but thanks to modern advertising no one believes it anymore.

No bubbler, raw papers...did you clean your bubbler?..i don't know how many times i think it's off then i clean it and voila`!..it doesn't even have to be really dirty..just makes such a difference..know how i know?..it's them BOTH.. or you just might have to take a few weeks off..my money's on your favorite device
BumpThese are pics of next round at 47 days flower to give an idea of foxtailing. I add calmag after I've ppm'd base nutes. also koolbloom liquid in weeks 4-7. They can't get enough magnesium. The widow hits much better than the blackberry but still neither one is FIRE!!! Maybe 67-72 days is too early to chop but the amber trichs have always been there.
This is next round day 47. CalMag issues have been addressed. Thanks everyone again for you insights.

doesn't that drive your ppm's up?I use chem nutes,,,
Jack's Citrus FeED 20-10-20 4.9% sulfur
Jack's Aquagold 7-15-30 9% sulfur
Gypsum (Calcium Sulfate) 18% sulfur
Epsom (Magnesium Sulfate) 13% sulfur
Potassium Sulfate 0-0-50 18% sulfur
I make sure my girls have plenty
Have never checked, never owned a meter and I don't mix all it together, I give them different things at different times based on their needs and the beauty of sulfates is they don't affect PH and are readily available to the plantdoesn't that drive your ppm's up?
have you started any new meds over this harvest..specifically brain? for ADD or depression?..hahahaa that can effect.No bubbler, raw papers...
i'm starting GH floraduo A/B..B bottle has 2% sulfer so i can't wait to see.Have never checked, never owned a meter and I don't mix all it together, I give them different things at different times based on their needs and the beauty of sulfates is they don't affect PH and are readily available to the plant
i love how you have an exclamation point after, "his are!". right after you state that not all plants will be happy a 350 ppm like you've actually done this lolRead the thread I linked above.
But since you're not going to:
He explains and tells you where you can find more info. Plenty of sources recommend to use the lowest amount of fertilizer as necessary. It's called a point of diminishing returns. Like I said not all plants will be happy at 350ppm, his are! And they're fat frosted nuggets. Plants will only use so much fertilizer at any given time, just because you have 1200+ppm doesn't mean your plants are using that efficiently.
That 350-380ppm (0.5 scale, 0.7EC) was test to see how low I could go. I'm sure, knowing not all my tap water contents is useful, I could go actually lower, like 250-300ppm. This is largely because the ratios I give align with the ratios the plant uses. I could double the PPM with N alone (not without getting too dark leaves though).ya, i read the numbers the first time you posted them. if indeed you've read plenty, please provide a link. id love to see where this is happening besides sativieds journal. if this has become common place its news to me.
Funny thing is, it 'was' kind of common. I posted several examples of others in that thread.if this has become common place its news to me.
Thanks, and no problem. Many of the who I believe to be the better or at least more experienced hydro growers in this forum don't bother arguing with those who run 1000+ because it suggests those are doing something wrong and people generally don't like hearing that. The real message is really that that little bit of extra people try to get out of it by choosing for more, can often be achieved by going for a little less, so yes, less is more. Especially if that 'more' is a result of the typical approach of trying to see how much a plant can take.Sorry, to use you as an example but I was checking your post right before I found this one and mentioned how I saw you run so low. I myself stay in the 600ppm-ish area mostly and have no problems and nice harvest. I wasn't trying to start an argument with AW, just was saying "less is more"sometimes. Cheers and your grows always look nice mate.
is there any sulpherHave never checked, never owned a meter and I don't mix all it together, I give them different things at different times based on their needs and the beauty of sulfates is they don't affect PH and are readily available to the plant
so home and garden line. any additives? calmag? do you buy them in N P and K bottles or is it the premixed? you know what? i can see kinda what your saying but what your implying is that the folks on here know when the plants are feeding hard vs. not feeding. thats a tough case to crack for the regular guy.That 350-380ppm (0.5 scale, 0.7EC) was test to see how low I could go. I'm sure, knowing not all my tap water contents is useful, I could go actually lower, like 250-300ppm. This is largely because the ratios I give align with the ratios the plant uses. I could double the PPM with N alone (not without getting too dark leaves though).
I don't actually recommend 0.7EC except for the first week and last week (little less even at the end). Instead, 1.0EC. 450-500ppm. I started with 1100+ run, nearly the complete H&G line. I tried 650-ish ppm after that, 450-480, and the 350-ish run. I get the same amount (17-18 oz, veg and transition with 400w, flower with 600w), and definitely no less frosty (if anything, on the contrary). I use only base nutes (H&G Aqua Flakes), and nitric acid for pH down (don't use phosphor for down).
What I mentioned several times too though is that I don't actually use that much less nutes running 350 opposed to 600 or so, I just add it more often. If you drop all the nutes it needs for a week in the rez, it will be imbalanced near the end of the week. That is in fact what often causes deficiencies, not a too low ppm, but imbalance caused by a shortage or excessive amount of one or more elements.
I've grown different phenos and completely different strains (100% indica vs sativa-dom) from the same rez. It is not as much strain dependent as some suggest. There are heavy feeding mediums though... and in DWC there's no medium that buffers. We had a decent discussion about PPM and amount of nutes at https://www.rollitup.org/t/why-are-my-ppms-going-up-now.835107/page-2 (the links to the attachments in that example run are working, thumbs don't show up for me though)
I do run a little higher in dwc than in NFT (/DFT/Flooded tubes), and yet a little higher in coco and hempy, but still 650 or lower. I actually top off a gallon of my NFT rez, raise ppm (mostly N), and then give it to coco or hempy.
I've convinced a few people running high ppms to try 500-600 instead of 1000+ and the responses are always the same "My plants look much healthier now". And healthy plants that have enough of everything, not too little, not too much, is what creates potent bud, as in allows it to reach it genetic potential easier.
Funny thing is, it 'was' kind of common. I posted several examples of others in that thread.

Reach that optimal zone for all environmental factors and the plant will do the rest. Plants don't want more, they don't want too little, they want "enough".
Just enoughis there any sulpher
I started with nearly the complete line, both veg and flower additives, even shooting powder (everything that was in a starter kit), but no longer use any additives. H&G Hydro, Aqua Flakes (used both, use the latter) contain plenty of Calcium and Magnesium as I've pointed out in many threads. Calmag is hype based on a common problem with sol (the lime buffer running out). Every complete line contains plenty of Calcium and Mg.is tso home and garden line. any additives? calmag? do you buy them in N P and K bottles or is it the premixed?
I don't see directly how I implied that, the plants are always 'feeding', 24hrs a day. Sometimes harder because they drink more (which is really what 'feeds' them indirectly, plants don't eat)i can see kinda what your saying but what your implying is that the folks on here know when the plants are feeding hard vs. not feeding. thats a tough case to crack for the regular guy.
Half of that 350 is from my tap water already. I realize it sounds really really low, but it in practice isn't. And no, that wasn't just the first and the last week, not what I said. The reason I run 450-500 is to avoid nute shock and because it's a little more convenient, not because 350 resulted in deficiencies.i applaud your results but feel that most guys who try to duplicate your results may end up short if 350 through mid flower is what your telling them to do. by the sounds of things thats just week one and the final week and that you just end up using nutes more often.
glad we figured that out. some guy was trying to say...well we know.
Ok, but your preference and believe do not align with how plants operate. The high tech greenhouses in NL worked closely together with labs and universities to determine an EC range for many crops which looks similar to that curve. Not a maximum. If you want to feed more nutes than needed, you have to breed that improved version of the plant first. It's a rather well known fact that more is often not more when it comes to plants, especially outside the cannabis industry with all the scamming nutrient companies.either way, healthy looking in dwc at up to 11ish wasn't a problem for me, like the most lush looking forest ever. i also prefer the go hard or go home approach which states clearly that, if you don't go as hard as possible then you sold yourself short. i also don't go harder than 650 in coco. i believe that more is more.
The image is not a concrete representation of ppm levels but the zone of intolerance is where you kill your plants slowly or quickly. So we know it's not that far. That 1000ppm could still be in the optimal zone (more likely in the stress zone, but not that level of the curve), but at the lower end of the curve, where the curve can mean quality and quantity. Same thing goes for amount of water, light, CO2, ventilation, root zone (ions in water), and literally every other factor that influences the environment of the plant. A plant grows itself, "go hard" in the context of growing plants means going hard for an optimal environment, not going hard for max or treating them like pigs or geese (though even those have a genetic limit).but just to clear it all up, is the 1000 plus iypo past the "zone of stress", or into it? or past it and into the zone of intolerance?
Looks great, lush, dark green. Leaves look very similar to my high ppm runs.

Color and plastic gloss look great perhaps but really is taking it too far (N in this case). That was 1000+ppm with several additives.
If you keep it up you will likely get rusty brown spots on fans later in the cycle even if you don't burn them. Leaves will likely get harder and crispier too.
The thriving force for plants is water potential, the air pulls water out of leaves, leaves suck water through plants pulling ions close enough to its roots for uptake. Typical argument in defoliation threads is that leaves shouldn't be removed because they are the solar panels, while in fact they are so much more. Keep the leaves happy, and the plant will thrive (hence the phrase reading leaves). Not saying 1000ppm leads to crappy shwag, but when it comes to pushing the plant to max yield and potency, just as the darkness of the green of leaves, more is not more.
This is what 350-380ppm (in NFT...) mid-flower looks like, and that's just a fan leaf:
