Calling all biobucketeers!

[rule35sub1]

Hey Ray, first off those guys don't use bio buckets.
I have grown in bio buckets for years. The reason you're supposed to use tap water is cuz of the elements and minerals in it. If you are going to go with RO water, make sure you add some cal/mag. Don't mess with the ph, the system corrects itself. I believe your water is too warm or you have dead spots where the water is not circulating. What is your water temps at? Get those temps down to 68F. This should correct your problems. The only time I have ever ran into plants looking like yours was when I had the water at 80F for too long.

I have been using all 3 parts in the same amounts!! (That is what it says on the label)

Follow the 1/2 strength recipe I suggested.

 

[Cranberry]

Hello Ray: Nice set up

Since you dumped your bb and are running an over sized dwc system with gh 3 part you might want to add 1tsp of epson salt to five gallons of water. This is a common practice with ghflora. As to your answer its a zinc problem.

I had the same problems a while back and just added epson salt. Good Luck

Hello!

Hello!

rule35sub1: very informative answer my friend, thank you! Yes, the water is too warm, that's it. Tomorrow, brand new chiller arrives to help fight the temps.

Blackvelvet: Thank you for you help, but may I ask you if you had personal experience with that formula in BB? Because if I recall correctly, BigToke used all 3 in same amounts... (I will go check, I could be wrong)


Hey Cranberry, nice to see you too. Its just that your answer got me ever more confused.... epsom salt from wiki;

Agricultural use In agriculture and gardening, magnesium sulfate is used to correct magnesium deficiency in soil (magnesium is an essential element in the chlorophyll molecule). It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, and tomatoes. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic lime) is its high solubility.​

So we have magnesium in the epsom salt and you have mentioned zinc deficencie.... I tought that Calcium and Magnesium are connected? Or do certain elements become unavalible to the plants at higher temperatures?

---

I have looked everywhere and I cant get the epsom salts. I did add some tap water, but I dont think it should do enough. Can I apply magnesium in some other form, I know I can get it in liquid. Are there any other elements that should be taken care of?

I really aprichiate your help guys! This hydro world is tough Big thanks to everyone!

Ray

At 68F, all nutrient salts are soluble, perfect temperature for water. GH 3 part, I would go 321 during veg and 123 during bloom. I also add epsom salt, you can purchase it at any drug or grocery store, during the veg stage, 1 tablespoon per 4 gallons of water in the res.

 

[Ray of Light]

Thank you rule! You are fast

Yeah... cant get this in europe... I have been asking everywhere where they have souch stuff and nobody even knew what that is. Europe is quite different than USA, you know I found epsom salt in a growshop in holland... will have to order asap.

And this 321 and 123... stands for MGB?

 

[raygun]

Hey Sub and Ray I have been running bio buckets for a few years now as well and i 2nd the warm temps but will also advise that with hard water to start i would supplement with RO at least 1/3. I have worse water than you close to 800ppm and that same 8pH. While the pH will balence out when you keep adding hard tap water you could run in to build up. I run a 50/50 mix and that works out great. keep those temps down and watch for dead spots (individual plants with symptoms not all is a good indicator)

I believe the 123 321 refers to the GH bottle dose recomendations. I use Floranova from GH and it works awesome.
Do you have this on an auto top off? That help my grow dramatically to keep things more regulated and not so much fluxuations. I only have 4, 3gal bucket in a closet so my total water in the system at any time is less than 20. As the roots fill in the buckets the less water is in the system and i actually get to close to 10 gal total by harvest so auto-topoff is esssential for me.
Hope all goes well and things get better wtih the chiller.

 

[Ray of Light]

Just a quick drop-in...

Just a quick drop-in...

Thanks for the imput!

I installed the chiller today, temp droped from 25° to 24° in two, three hours but real results will follow in the next days. I also got a hand on the thing called Epsom Salt, they call it totaly something different here I will apply a dosage in the res and spray them foliary to help them recover. In a matter of days I will have to swich to flowering.

Oh yeah and the top off thighy.... totaly forgot about that. I will contruct it in the next days.

All the best
Ray

Caution...magnesium overload

Caution...magnesium overload

I also add epsom salt, you can purchase it at any drug or grocery store, during the veg stage, 1 tablespoon per 4 gallons of water in the res.

I don't suggest using this rate. Its adding 105 ppm magnesium! With full strength 3 part and this epsom rate, mg would be 145 ppm! Plants in hydro only need about 30-50.

Lucas sticky in the hydro grow section:

GH's baseline Flora Series, the 3 bottles, green purple and red, (different from Flora Nova series) veg formula
GH 15grow, 10micro, 5bloom in 1 gallon of water
211 n
46 p
263 k
40 mg

If your really into magnesium add 15ppm more. (total 55 ppm mg) This would be 1/8 teaspoon epsom salts in 1 gallon of water. I doubt you will need more than this. Ok, ok...I know some of you are mag freaks. I wouldn't go over 70 ppm mg though. 1/4 teaspoon per gallon epsom salts with the 3 part.

Oh yeah, and if you use 1/2 strength of the above 3 part recipe, you would use 1/2-2/3 strength of the epsom rate suggested.

I don't suggest using this rate. Its adding 105 ppm magnesium! With full strength 3 part and this epsom rate, mg would be 145 ppm! Plants in hydro only need about 30-50.

Actually, according to Mel Frank, at different stages of their growth cannabis plants can use up to 80 ppm of Mg. I believe the 'target' numbers according to his "Marijuana Growers Insider's Guide" work out to : N P K Mg 100-100-200-60. I have occasionally seen Mg deficiency at lower levels of Mg and higher levels of K, and personally don't recomend using below 45-50 ppm Mg or more than 200-225 ppm of K.

 

[rule35sub1]

123 gmb, 321 gmb

 

[Grat3fulh3ad]

That is too much Mg, though... the rate I use is actually similar to what BlackVelvet suggests... I use 1gram per gallon which roughly works out to a teaspoon in a 5 gallon bucket.

You, sir...are a scholar and a gentleman. 'The voice of reason' is also 'the example of class'. You have set a new, higher standard for the members of this forum. Thank you.

Yeah that too...most definitely No doubting that Head is good people but you sure come off sounding odd. It's fantastic to have an extensive vocabulary but it comes off as a little funny. I mean, all Head did was say that he was in agreement with something BV had said( ). All of a sudden, he is the end-all answer to growing. Head...you have a fan(atic). Here's to Head and all of his good advice. Here is to Chuck, who is one die short of a pair of dice.

*snuff* *snuff* .... this smells like offtopic, guys. Come on guys, why cant we all get along...


/I've got a private message and i am guessing it is about this thread, since i didnt participate on any other .... well I cant read it, spam protection or something.... I need to wait till 50 posts, maybe that person could write the PM here...

thank you
have a great day

[Blackvelvet]

Better get your post count up to 50 asap. Go to the introduce yourself theads and say hello. Go over to the stoners crash pad with joint in hand (no joint no go!) and bump the if your high thread.

Blackvelvet does not really condone any of these turbo posting actions. He's drunk and knows Dutchgrown is always lurking.

By the way, she's hot...




Lmao.

 

[Ray of Light]

I guess that PM will just have to wait... I dont have time to write bullshit posts...




























PH 5.6
EC 0.98
Water temp: 68F, 70F at heat peaks

I have added 80 grams of epsom salts couple of days ago + foliar spraying, that raised ec for ~0.08.

It seem they are doing better, what do you think? Still vegging tho.... I just cant get myself to flip the timer

It's amazing ... some plants have only grown like 5 inch from the start but some went up and became real trees... the only thing i would think of is stress? But why souch a big difference

 

[rule35sub1]

I wrote that pm ray.
It's not important, when u get 50 posts, u can read it.

-- Found answer to that in SQ's threads.... he reccomends prestressing clones before putting them in the hydro system because than weak ones stay behind all trough flowering... that's what's happening to me also.
