Coco Growers Unite!

hey Jberry - even though i lowered the MagiCal dosage down to 3ml/gal after you first told me, I'm still seeing that same pattern of lower leaves shriveling up - pretty much the same way I originally posted in some pics a week ago? I even saw one or 2 tonight that almost makes me think its a Potassium issue - maybe not, sure did match some descriptions of Potassium that I was reading in CANNATalk today.

per the few of you guys responses above, I gave each one 1gal per container tonight per the 2qt's I had been.

I did up the PK 13/14 to ~4ml/gal this feeding. I am just now in week 4. Other than that, just 10ml/gal of A+B.

One thing I have noticed, a few leaves at the top of the plant have gone bright yellow, like someone has spilt yellow paint on them, real sporadic patterns. Mag def? I'll get a pic later and post it.

I looked at the latest picks and it does look like a potassium issue which usually is not a issue in coco but it can be if you have a long vegging period. The potassium in the coco depletes after about 4-5 weeks.

Honestly though, I think that your potassium issue is caused by other problems...

1) Deficiency and Lockout issues take a while to show visually. By the time you see the first signs of a problem, it has likely been a problem for while at that point, and then if you spend more time watching it progress, then it could potentially be a month old problem that has only become visually bad in the last week... Point being that you used that Nitrogen product a while back that was high in Ammonium N. and that causes Potassium to become locked out... That is likely where the lockout began.

2) Until recently you have been using around 10ml per gal of cal/mag plus the calcium in the canna a/b base nutes, plus the calcium in your water source... All together that probably puts your total calcium PPM's in the neighborhood of around 800 ppm i would guess and that is just the calcium alone... Your total ppm is probably around twice that. That is too much calcium and too much calcium is one of leading causes of Potassium lockout... I'm almost positive your problem is mainly due to using too much calcium.

3) Cold temps and high sodium/salt content is also another big cause of Potassium lockout and the water filter you use does not remove salts. So I'm guessing the unusable salts from your tap water have probably been accumulating in the coco since you haven't been getting the run-off you needed to flush the junk salts out. Also your EC was probably sky high when you were using all that Magical which was just adding insult to injury.

so how was the runoff dude. tell me if im wrong, but i'll bet when you got about half way through the second quart it was starting to leak out the bottom. but tell me something why were you so dead set on "2 QUARTS PER CONTAINER". now if its a thing where you are trying to conserve nutes, then i understand. but if that wasn't it, then why bro? just curious.

Has anyone seen a decreased yeild?

Nice...... definitley something i will remember.
appreciate that.

@Jberry. wow. that was a pretty good analysis. It totally sounds plausible. Should I just clearex this now? or just run a lot of water through with 2ml/gal of A+B?

why was I so set on the 2qts? Fukkin habit man. I dunno. Just sorta what I always did with soil.

That said, yeh there was decent run-off, didnt seem like 10 - 20% or anything.

my PPM has been under 1400 btw. I've had the PH steady at 5.8 and 5.9
the latest issue (and I've posted this a few times tonight, cus I got too much riding on this to have shit go south now) though:

View attachment 1081932

This is predominately on the Blue Dream, only top upper leaves. Not really wide spread amongst all the girls, only on a few, and not a lot of them per plant either. thank god. this doesnt look good, advice pls.

JB++++REP++++REP

Hello to all the coco heads I'm new and decided to start with coco things have been going good until now.I started my own thread but I figured I would post here to I'm having trouble with my jillybeans 4 of them they are in Botainacare cocogro did the 2 week stretch going on 1 week flower being fed Ionic bloom 2 tsp.,Ionic grow 1 tsp.,Liquid Karma 2 tsp.,Liquid Koolbloom 1/2 tsp.,and Cal-mag Plus 2 tsp. per gallon can anyone please tell me what's wrong.And ph is 6.0.

looks like it could be a fungus/disease... pull off the effected leaves and see if it continues. Sometimes a leaf stem will get semi broke at the base/branch and you wont notice until it starts to die off, but your pic sorta looks like a diseased leaf but im not positive.

has it been getting worse?

looks like a possible mag def.. what do the healthy leaves look like? dark green?, or pale green?

You probably have a lockout going... 10ml of cal/mag+ is a lot imo and the calcium is possibly locking out the mag.

are you using hard tap water?

try lowering your cal/mag+ to around 3-4 ml per gallon... Im not familiar with the content of Ionic nutes so i cant advise you there unless you provide all the percentages, ect., but I do know that 10 ml per gal. of Liquid Karma is going to raise your ec quite a bit because that stuff is strong... I would personally lower that to maybe 5ml (1tsp=5ml) per gallon or so because your overall ec is probably on the high end considering all your products/doses.

The healthy leaves are light green,I did as you suggested I cut outl the liquid koolbloom and lowered the cal-mag and liquid karma I gave them a flush and then feed them,hope this does something thanks for the reply jberry,oh and no hard water.

Now that your additives are cut back you may want to raise your base nutes? Are you the Ionic Grow/Bloom at full strength already?

That's exactly what I did I wasn't using full strength yet bottle says 4 tsp. per gallon I was doing 2 1/2 tsp. per gallon at the most so after the flush I gave them 4 tsp. per gallon good to know I was thinking right thanks again jberry.

I just put in a order for a Hanna tds meter can jberry or someone give me the range of ppm's for clones,veg,and flower

Coco

Coco

what seems to be the best way to do your flush?

and for how long

im into my 4th grow since switching to coco and have heard and used a couple of different ways

*ph'd water 5.8> 5-6days 7 litres of run off, im in 55litre pots

*final rinse for the last week, with RO (lowers ph to around 3-4)

*pinneapple juice 5mls/L last 3 feeds with run off(lowers ph around 3-4)

what really is this flush doing except flushing excess nutes out of the coco?
are we trying to deprive it of elements (N),(P),(K),(S),(FE),(MB)

as i see once you flush with ph'd water there is no nutrients left in the coco, so the plant will feed of its self causing its leaves to yellow up wich are signs of(N),(P),(K),(S),(FE),(MB) deficiencies

do we want the plant to feed from its-self for the last few days to give the plant some kind of deficiencies

what works best for maxium flavour and minimal loss in yeild???

hey dude whats going on man? what brand of coco/nutes are you using?
me personally i use Canna, and since i reuse my coco i dont flush it with sraight water. hell, if i wasnt reusing it i wouldnt flush with straight water.
what i do is at about week 6 to 6 1/2 i start to taper the nute strength down from 4ml per Liter(full strength) to 2ml per Liter(half strength). and in no way is there any chemical taste lingering in the inhale or exhale. for example i grow three different strains, well two strains , but of one i have the sativa and indica pheno. anyway, when they are done curing they all have their own disticnt aroma and flavor, on the inhale and the exhale.
but thats just the way i do it. i dont know, tell me if i'm wrong, buti dont want to cut my plant down while its "DYING OFF" and feeding off of itself. no, no, no i'd rather cut my plant down while it is at its best. full and healthy, and since the nutes were tapered down, and marijuana is so adaptable. the plants survive, and thrive till the day they die off of just enough nutes to where i have no chemical taste whatsoever.
but check this i believe that Canna requires no flush for their coco at all, i think. but i have found a good balance that works for me.

(N),(P),(K),(S),(FE),(MB) are not something I am seeking after in my smoke... If you can make the plant rid itself of these or anything else (other than terpines, thc and other psycho active componds) then it seems like a good idea.

If you wait until the plant is done packing on wait and is pretty much done with its life cycle to flush then it really shouldnt effect yiled at all and the stress from the flushing proccess will actually help with speeding up the final ripening stage.

Coco flushes fast and is easy to flush when compared to soil, so you are much less likely to have your yiled effected from flushing when you are using coco.

I've heard good things about pinapple juice but it may encourage algea as well.

my apologies if this was covered already (and i do need to go back and re-read this entire thread) - when flushing at the end when using 100% coco - how many times and how far b4 harvest?

also though - what if you wanted to go for the tops/upper canopy first, and then let lower stuff get another, say 5 - 7 days - would you just taper off nutes ike Zen suggests about 7 days out?

thnx

For rooted clones anywhere between 250 ppm to 650 ppm seems to be fine but just keep an eye out for deficiencies or overdoses at adjust as needed. These are all just basic guidlines and it is always recommended to do a little experimenting to see whats best for your environment and strain.

For growing in coco coir rough guidline:

Grow: 1.0 if using RO Water / 1.4 if using typical Tap Water

Grow/Bloom Transition: 1.8 (RO) / 2.0 (Tap)

Bloom: 2.0 (RO) / 2.4 (Tap)
