Root Rot set in instantly after nutrient change

[Billy the Mountain]

It would have to quite severe for a calcium deficiency to affect the roots.
Alternatively, root rot (aka pythium) can rarely be attributed to a calcium deficiency,
there's a myriad of more likely causes.

I tapered humidity off over about 10-11 days starting at 60 down to about 45 at day 10 until stems snap. After i bag them in breathable LB bags we use for transporting bud from dispensaries with 2 low end hygrometers and 2 bovedas at 62%. Bag stays about 58% for 3 weeks with a 30 minute burp a day

Yeah 45 is to low. You want it to hold 65 without bovida.

I also find those things suck the smell out from the buds.

I jar so it is 70s then burp to 60s.

I see, i was allot more worried about mold than i guess i should have been. I have heard the bovedas drawing the smell from bud before, but im in such a habit of using them in the dispensary that i guess i kinda just figured. Will keep this in mind on this upcoming harvest. Do you not believe going to the full i thin 10 part series from flora is worth it in dwc? The myth this is stinging from is that water has like none of the micros that soil provides, hear this all the time.

Are you asking if you actually need all 10 bottles from Floro series? Heck no!.

I grow flood drain hydro. 1 bag jacks tap. 1 back jacks cal nit. 1 bag empson salt.

Total cost was 10-15$ for nutes start to finish. And I say that only cause I had to pay 40$ for shipping. Total cost for nutes using AN was over 100$.

Start by going back to basics and don't be lured by manufacturers to use products intended for dirt, they're only after your money.

Choose a proven complete plant food and sterilizing agent. I use chlorine but you can also use H2O2(hydrogen peroxide). Work to keep biofilm at bay and focus on keeping pH stable as possible and study what's possible in terms of lowering surface tension.

Environment, environment, environment!

How to fix Cannabis Calcium Deficiency (Ca) Pics & Symptoms

Calcium deficiencies cause tiny brown spots that appear on new and middle growth. Learn how to fix this problem for good!

read about half way down on this. Is this website misleading? genuinly asking


"
Other Symptoms of Calcium Cannabis Deficiency
If a cannabis plant is affected by a calcium deficiency for too long, it may begin to show the following symptoms due to the lack of calcium.

• Stems become weak or flimsy and may crack easily
• Stems become hollow or show inner signs of decay
• Plant does not stand up well to heat
• Flowers/buds do not develop fully, or development is slow
• Roots appear weak or under-developed
• In severe calcium deficiencies, parts of roots may even die off or turn brown
• Roots are more susceptible to root problems like slimy root rot

I wouldn't put too much faith in what you find on that site. There is a lot of bad information and much of it is just cut and paste from other places on the web.

You're right on regarding the cut & paste info on growweedeasy.

OPs root rot occurred because of the addition of organics to a dwc system, not because of a calcium deficiency in an "almost perfect environment".

See ive done that my last 2 grows with just my tap water for flush and the base 3 (floraMicro, floraGrow, and floraBloom) and even after a 15 day flush with tap water, i get a taste that is almost like a dryer sheet. I dont know if it is my flush that is messed up or if it is lack of terps due to lack of growing medium. Any input?

I've been trimming for 12 hours and I'm too tired to go into a long drawn out explanation, but please switch to jack's 3-2-1 system. I can assure you if used properly you will grow the best tasting buds you've ever grown. Flushing is for toilets. There's nothing wrong with leeching for 4-7 days prior to harvest with plain water just as a soil grower would do as the plant is winding down it's life cycle, but starving your plants for 2 weeks prior to harvest is a really bad idea. I usually leech for 4 days before harvest. 7 days at the most. It's called leeching because to call it flushing is just asinine. You can run all the water in the great lakes through your plant and you aren't "flushing" anything out of the plant's tissue. Anyone that thinks "flushing" is a science based concept shows their fundamental lack of understanding how plants work. The purpose of leeching is to allow the plant to ripen without further fertilizer input the plant does not need. Flushing is for toilets. Leeching is for plants.

i thought "flushing" was just to get the main nutrients out of yor final product. Allowing the planmt to consume the nitrogen and stuff out of the leaves so that you dont taste them in your final product. If the plant after however many days is still very green and showing no signs of cannisbalising isnt it a sign that there is still chemicals in your plant? This is the only reason i went so long, i was told 5-7 days is more than enough is DWC. However i have yet to see this occur. I have to be messing the leeching process up for sure, as far as my understanding is. Again not being nasty, just picking brains and trying to find answers lol. I will check out the Jacks line. Also my "leech" water is not RO, i dont have an RO system yet, im using tap water at about 120ppm

Leeching can be done with tap water too. It just means no fertilizer. The plant's tissue absorbs elements throughout it's lifecycle from start to finish. Most fertilizer companies such as general hydroponics recommend far too high an EC using far too many unnecessary products in their feed charts. Over feeding fertilizer from beginning to end will cause an excessive amount of elements to accumulate in the plant's tissue. Discontinuing fertilizer inputs and feeding plain water for 7-14 days is not going to cause those accumulated elements to simply vanish into thin air. Feed the plant a balanced fertilizer from beginning to end and you won't have to worry about "flushing" an over accumulation of elements out of your plant's tissue which is an impossibility. A good example of this is if you take a cut white rose and place it in a cup of water with food dye the flower will turn the color of the food dye by the following day. No amount of plain water will then "flush" that dye out of the plant's tissue. The dye will remain. You dig?

That makes sense, except thats food dye. Not nitrogen which the plant should get from anywhere it can, thats why its called a "mobile nutrient". By leeching the nutrients according to every book ive ever read (including oaksterdam textbooks) you are sucking them from the leaves, which a plant will do automatically at the end of its life, although your way too amber at that point which is why people force it by starving the reservior. I know this flushing/not flushing thing is a big debate on the internet...but its nothing like putting food dye in a rose. When you leech nitrogen for instance out of a plant the leaves should turn yellow because the plant will literally eat itself. Its called cannabalizing

Flushing is a flawed remedy for poor growing practices. Nothing more. Feed your plants a balanced fertilizer from start to finish at a reasonable ec. Plain water irrigation 3-4 days before harvest. Same as you would do with soil. Uncle Ben over @ ICMAG grew some of the frostiest buds I've ever seen and his leaves stayed green all the way to harvest day. He ran jack's 20-20-20 start to finish. His many photos speak for themselves. If you understand and exercise proper plant nutrition you don't have to "flush" anything out of your plants. Typically the people preaching the flush nonsense are the same growers running 10 different bottles of nutrients with a 2.0+ EC in their reservoir. Yeah, I'd flush every dam bit of that down the toilet

I see. I honestly really wanna see a side by side of flushing and not flushing on clones in the same tent. I wanna see the difference in color at the end and taste. i will be checking out jacks and probably gunna run it sometime soon. I know were way off topic of the title of the thread BUT this flush thing always sparks my interest to hear peoples experiences. I work many dispensaries and grows throughout Oklahoma and its a HUUUGE deal to some people and basically a myth to others lol. Im trying to get my hands on grow experience up, just cuz i can read a book and understand things doesnt really mean i can go into a grow and UNDERSTAND things ya know? Kinda want the hands on and tweaking things to get the reality of things. Cheers for all your help

Also turns out, i was getting root rot after changing nutes (im almost 100% certain because its been 2 changes now no problem after i learned this) because a combination of not diluting ph up and down before going into to reservoir, and stirring that ph up and down IN the reservoir basically destroying all my biofilm on the roots. I stopped moving the roots aggressively and my root ball has almost doubled and is not turning the brown color that i was originally attributing to severe calcium deficiency. And because of this root rot issue the plant showed signs of deficiencies that werent really there, but was just root issues. Ahhhh how i love the complications of growing.
