Hey everybody

What's up gaius? Hows it goin bro, long time no see.

Hey, I'm having some problems w/ my new coco setup. I tried using PBP grow and Cal-mag instead of just getting Coco nutes. I've been using PBP line a while and it's always done me right until now.

anyways, trust me when I say it's not a Mg def, although it looks like one. It was 5ml/gal calmag + PBP grow to 1.6 EC, ph of 5.9 to 6.1. Ph was at 5.2 for a few days when my meter died on me, but then I pickked it up to 6.0 4 days ago, and it's only getting worse. I diluted the rez slightly, then added in another2ml/gal Calmag and 2ml/gal Sweet, which has a good amount of Mg in it too, at which point the problem progressed faster then anytime prior. So, I drained and refilled the rez with RO water, and set it at 1.1 EC.

You guys have any ideas?

YOur locking up you mag and potassium.... here is a link to canna with some pictures and explantions... I have found it the best resource for coco growing..

I had this prob too going from canna a&b to monkey juice.... I feel for ya...

Hey gaiusmarius, I would just like 2 thank you for all the good info you supplied me with earlier in this thred. Here is the link to my previous post to refresh if you forgot. http://www.icmag.com/ic/showthread.php?t=23140&page=26&pp=15&highlight=ph

So far I am loving the new coco setup, and have been running it as a top fed recirculating system. I am in the first week of flowering right now, but I can definentally say that they are growing very fast. I decided to stick with that coarse coco, and am currently giving the Monkey Juice from AN a run with it. I am also going to be using some other addatives including their Hammerhead P/K 9/18. Just thought I'd stop by and share my coco on this site, and will post some more pics as things progress. This is my first time in coco (soil grower for years), and I have very little experiences in hydro, so hopefully I dont screw this up . Here are some pics of veg, with a cheap ($20 dollar) recirculating drip setup made out of a oil drain. It held 2 gallons of water, and worked great for their 9 days of veg. Also are some pics of them starting out in bloom. Oh ya, the roots are fk'n amazing too.

Excellent, this is what I like to see.

Profits are tha best coco. Period.

Peace,
Nandro

Thanks guys, but the coco I'm using is actually Piece Coir from Sunleaves. It's very coarse stuff, and drains well with tons of air. Here is a pic of the compressed brick of the stuff. I took some precautions with it, and filled up a trashcan with a bunch of small holes in the bottom, and ran water through it untill it came out almost clear with a ppm of around 100. This stuff out of the brick has a starting ppm of around 600, so I wanted to get it as low as possible b4 I started.

Hey Mo Budz,

it's looking good so far man, keep up the good work and you will soon be up to you neck in plants. why not start a thread, it will be a good record for you and will help others in similar situations.

Any coarse coco is a winner in my book

Hey my fellow growers.
I have been having a difficult time with my coco.
Some may remember I mixed up 40 cu ft. of coco and perlite and I couldn't get the ph below 6.4-6.3.
Now I went out and got a fresh bale of botainacare and have flushed a 5kg bale 3 times with ph'd water @ 5.5.
I started out with a ppm of 400 and now it's down to 60 but the PH will not budge.
I hear two different ways of checking coco. One is to take 1 part coco to 10 parts water and mix,drain and check.
Others say to check runoff.
I took a 5"x5"x7" planter and filled it with coco and proceded to flush the hell out of it. I poured no less than 3 gallons through it. (this is after the initial 3 flushes.)
Best runoff I can get is 6.3........
Any suggestion?
Stay peacefull

I know this is a necro post but I am having the same problems. I didn't see much advise as to how to correct this. The reason I am posting is that I have some clones that are SERIOUSLY defficient. They began their life in B-cuzz coco and they have never been healthy. I have 2 moms that are doing really nice but these little ones just can't get what they need. I am embarrased to post a pic but I guess I should.

I have tried everything! Less water, less nutes, cal mag, micro nutes, potassium, Flushing...everything. I am in a tailspin here. I began with PBP grow when the girls first went into cups. I probably transplanted a bit early. Ever since they were clones they have been slowly yellowing short bits of growth here and there but mostly stunted their whole life(4 weeks!). I just purchased some coco nutes and Canna coco.

I tested them by combining 300 ml tap water (100ppm and 8.0 ph) and 200 ml coco. I filtered and tested the h2o after 45 mins and the b-cuzz was 640 ppm/6.35ph. The canna was 330ppm/6.40ph.

At this point I have some canna coco nutes mixed up at 450ppm(hanna meter at 5.0 conv.) with the B-cuzz root stimulator. I sprayed with 1/4 strength PBP grow as foliar because they are just so pale and brittle.

This is my second grow and I had the first grow stall out and act very similar at 5 weeks into flower. I nursed the grow out with no new growth but never could fix the prob. I would love to know if anyone knows for sure what the burnt leaves is from. Some defficiencies burn leaves but so does high EC.

The ph outflow of the plants is 6.5-6.7 so I have been trying to bring it down so the micro nutrients will be available but it is slow going dropping the ph in coco.

I am thinking K def. because the older leaves are burning first and there are rust spots on the leaves that burned first. The whole plant is chlorotic though and the new growth is affected so that is why I thought maybe an immobile element problem..

Edit...Temp 75/65 Watts... 1000hps at 4 ft from tops humidity...40 lights on/70 lights off

How high would you guys have your Canna coco A-B nute's ppms for clones with small roots? I am hoping I can get these things happy so I can flower them.....here's the PICS...

 

[gaiusmarius]

give them an ec of 1.0 that's, 1.5 ml of A+B each per lt water. once transplanted like in the first pic in coco, they will soon be ok, if they have rots that are alive. it might take them a while to get cracking again, but you should be able to achieve it. a nice root tonic added to A+B at 1.5 ml per lt. will soon have them producing new healthy growth.

did you spray your plants while the lights were on? because that's what clones can look like if you spray them or dunk them while the hps is on. the water droplets act like a lens and cause the light to burn your clones leaves.

anyway good luck sorting it out.

 

[Caligrown]

Thanks Gaiusmarius! I have been seeing in the forum that you know your stuff and you use the canna as well. Thanks for the pointers.

A couple of things I left out. I added early on enzymes, mychorrizae, and Rhizotonic. I noticed the resi ph raising so I stopped using the additives. Would the fungi affect what EC I should be using? ie. better uptake?

Also my tap water is 100ppm so should I add 100 ppm to my 1.0 canna EC?

Spread the love... Jay

 

[gaiusmarius]

no don't add your tap water to your ec. cannas recomendations are rather on the high side, not every strain will do it's best with that much. so work your way up slowly and watch your plants to see how they look the happiest. as for the rhizotonic, it's known to push your ph up, this is no problem you just add ph minus till you have the requited ph.

but like i have said before, you can achieve very good results using nothing other then canna coco A+B at the correct dose and ph. i know, i have done it many times.

 

[JackKerouac]

Is that a MicroGarden with the drippers? I thought about picking one of those up.

Holy crap, that is the angriest coco I have ever seen. Today I went with the Boss blocks instead of the SunLeaves, because it seems like it would dry out or not have any place for the roots to go.

Lookin' good!

 

[Mo Budz]

Thanks Jack. It is actually a homemade recirculating drip setup. I used a oil drain pan bought at wallmart for 10 dollars. A 66gph submersable pump (tiny one). 1/2 inch line, with 1/8th inch drippers. The drain pan holds 2 gallons perfectally, all I had to do was cut an opening for the pump to go inside, cut a piece of screen to keep the coco from goin into the res, and a little tray to sit inside of the pan for the containers. Total construction was around 25 dollars. Worked great too.

 

[Caligrown]

I love the small recirc setup bro... How often do you add/replace nutes with the little plants?

Is it hard to keep them moist? What feed schedule do you use?

 

[Mo Budz]

Thanks. I only veg for 9 days, so in that time I probably added 1 to 1 1/2 gallons of water all together. And I have it setup on a timer to water 5 times a day for 5 minutes on a 20hr on 4hr off light cycle.

 

[Caligrown]

I really like the setup man..There is no question you are treating the coco as hydro and you girls are loving it. A friend set me up with the b-cuzz coir dust. I think after seeing your pics that I know most of my problem. I had 50/50 coir and perlite in cups and the stuff holds so much water that the roots were being stunted. I see that the roots love the space they have in your coco chunk setup.

I do think that later on the coco dust would be great for someone hand watering. The plants drink so much when they are larger that you would need the water retention if you only water once a day.

I am going to start at least rooting in something course like you have but my hydro shop doesn't carry anything course(checked it out today) and I will get killed on shipping if I order online. I'll find something though.

One more thing...It looked like you were using grow bags in one of your pics? If so what is you take on them?

 

[Mo Budz]

That coir I use is super cheap stuff. $10.00 for a 2.5 yard bale. I love the grow bags for my soil plants. This is my first experience with coco and I have very little experience with hydro, but I have grow in soil for years. My soil gets vegged in the same 3.5inch containers for 9 days, and then 1 gallon grow bags to flower in. I get really good results with soil, but I have been wanting to try coco for some time now, and so far I am really impressed with their growth. The main reason I like the bags is because they are cheap, and disposable. After a grow, I empty the soil from them, and throw em in the recycle side of my can. Much better then cleaning containers after each grow.

 

[JackKerouac]

I have a question about Clearex-

I was recently gifted a bottle to try out. I flush every Sunday with plain pH'd water, but would clearex help? I haven't had any salt buildup problems thus far. Doing a search, GM recommends using Clearex only after harvest to get the salts out.

I don't want to let it go to waste. Would this give any benefit?

 

[gaiusmarius]

clearex is not a product i know personally, but it sounds like its a flushing spplement? so you could use it for the end flush before harvest, or you coulduse it for your normal flushes, it's really up to you. i have always done my flushing with plain old tap water at ph 6.0

Thanx guys

Thanx guys

Hey everybody.

I wanted to pop in and thank everybody for thier help and suggestions. To answer a few of the thoughts though: It was def not overwatering, and the leaves which had the symptoms were never sprayed. They were actually growing amazingly fast when those probs popped up.

I appologize for not chiming back in to let you guys in on the situation.

Anyways, I switched to Canna and reduced the concentration to 1.0 for a few days and everything cleared up. I raised it from there to 1.2, which is where it looks like they are happy. I am pretty sure in was a Mg/Ca lockout from too high K and the concentration in general was too high at 1.6 considering I had just transplanted and what not. That was a rookie move I shouldn't have made, but I was all giddy about getting my hydro set back up after running soil for a couple runs.

So, things are going great. I pruned the crap out of half my crop to see how they would respond, and so far I think it should be positive, with less spindly growth and nice, heavy tops. They filled in very fast. I've got 36plants/4' x 4' tray.

I ran and drained bushmaster last week, and they are now about 10 days into flower, and although they are not loading up with flowers yet, the growth is developing extremely compact.

I guess I'm running Canna base nutrients, with all the Botanicare additives (Liquid Karma, Sweet, Hydrogaurd) that I've been used to and love so much. I'm also going to be using the trio from Eel river hydro: Bushmaster, Gravity, and Purple Maxx. I've ran the Bushmaster lots of times, and love the shit, and am quite eager to see how the gravity and Purple maxx work out.

I threw my CO2 tank in the room a couple days ago as well, so I'm running my temps around 90 with 1500ppm CO2.

This shit is going to rock. I'll get some picks up on a thread one of these days. My lights run nights and I'm going to school at night as well, so I space taking pics.

Peace out Everybody, and I'll post a link when I start my thread.
