Is this a copper deficiency, and should it be flushed?

[since1991]

Yikes! Your plants were looking good awhile ago. I seriously don't know why you are having so many issues. Just to speculate I would say you overfed and the temps got too low. I've never had issues like your experiencing using blumats and 100% coco. I stay under 800 ppm, sometimes a little more but not by much and the 800 ppm level is during the first few weeks of flower. I start cutting back mid flower. I never flush or top water. I also use a small space heater in my tent to keep the temps up during lights off and I run the lights at night when it's colder letting the light heat the tent. The space heater runs during the day when the lights are off and it's warmed up enough that the space heater keeps the tent around 68 - 70 degrees.

Those plants are not going to recover significantly by harvest time. I hate to say it but those buds are not likely to get much bigger. Those plants are stressed out, overfed, and likely drowning in that soaking wet coco after all the water you flushed through. Never flush straight water through coco this late into a grow. It screws things up. I don't think you have enough time for those to recover significantly. You're too far along. If I were you I would yank out the blumats and hand water for the remainder of the grow with 1/4 strength nutrients.

That's pretty much all I can offer. You seem to have so many issues and as soon as you fix one another pops up. I think your cursed. Just joking but man you sure have a bunch of issues. Sorry not to be of more help but it really doesn't matter that much at this point. Those plants are already screwed. Are you positive your giving us the whole story on what you have been feeding?

This ^^^ Its something your doing..did..or not doing consistently. That's for sure. It could be a bad batch of coco from the store but I highly doubt it. Could be a bad batch of nutes..I doubt it. Could be a bad meter..again...highly doubtful. It's something grower practice related.

you HAVE to get some run off in coco, or the salts will build up and eat your roots. at least once a week you NEED to top water till you get a little run off.

I always thought that as well but I have numerous successful harvests of beautiful plants using coco and blumats without a drop of runoff the entire grow. The key is to never overfeed. I know there is a bunch of differing opinions on runoff and when I was hand watering I watered until runoff. I don't with blumats and my plants grow great all the way to harvest.

Like I said..many growers have no problems with zero runoff. Whatever way or method of fertigation. But as a general rule or good practice...its a good idea to get some. Whether it's every feed..daily..weekly or whatever. Especially when using a hydroponic substrate like coco c oir or rockwool .

you're walking a thin line, and while you are apparently able to walk it, i doubt a lot of people are. the most prevalent problem on this whole site is over feeding. anyone who is guilty of that needs to get some run off.

I agree that the root cause of most issues on this site is overfeeding.

Lulz.

I’m done. I gave it a shot, I’m done. I must be retarded to put myself through this nonsense when I live in a recreational legal state and weeds cheap. Fuck it, wish I could say it was fun.

Peace out, y’alls. I do appreciate the help. Best of luck to you all.

 

[Daveindiego]

Regarding my feedings....

Once AGAIN, other than one week where it got up to 1100, by using 1/2 recommendation levels of nutrients, I’ve been running minimal Base, CalMag, during veg I used 1ml/ gal of House and Garden Roots Excelurator. At week 3 of flower I added 1ml/gal of Flower enhancer.

The last 2 weeks have been fed at less than 500ppms.

 

[since1991]

I wouldn't give up so fast broseph. I started 25 plus years ago and I couldn't grow a frikin toe nail much less some decent cannabis when I first started out. Some people take right to it...but most hit speed bumps until they get the hang of it. If you want close to free weed (indoors)...dont quit growing now. Lol

Don't give up. Maybe you should go to soil and make things easier. Mix some Ocean Forest and Happy Frog in equal portions with some added perlite. Don't feed anything until you start flowering and then only every couple watering's at half strength. Or make your own super soil and forget about feeding at all.

 

[since1991]

Yep. I always recommend promix and a simple one part like Dynagro or Ionic for new growers. Keep it simple. Limit the variables. I know of pro vet growers that started out like this and they go full circle right back to the basics. And they grow phenomenal indoor cannabis. It's a common c3 plant. Once you get it..you realize it's the strains that make all the difference. Don't quit. Soon will come a time whether you are a real grower and your hooked or a dabbled that tried it and moved on. But don't quit out of frustration. You haven't even got to that level yet. Your problems are very minor.

 

[since1991]

Or quit and buy it from huckster carpetbaggers like myself. Lol. Choice is yours. You already got the frikin equipment though. Not only would I not quit growing...I would attack this shit like a lion on a zebra. Gnarl this shit right up.

 

[natureboygrower]

what's the advantage of coco once you get it "dialed in" as they say?
op,don't give up.shit man,try another medium.i've been growing outside for 10+ years using coots soil mix for the last 3.i started an indoor last fall and just went with promix to get my feet wet on my first run.on my second grow i went with 100% coots mix for one plant,50/50 coots and promix on another,and 100% promix for two others.im on my 3rd run now and ive gone back to 100%promix and organicare ferts from botanicare.gl bro,youll get it all sorted out

Bro, after this go around, I really don’t know what I could have done to make it any simpler.

First time out the gate, and I sold my shit to a dispensary for 2400/pound. After that, it all went to shit.

The difference between the first time and the rest were using a tent. First time out the gate I had 70 plants in a room, being hand watered using a complete and total House and Garden 9 bottle nutrient system. Turned out great, except for the total yield.

Everything has gone to shit since, including cunt ass neighbors.

Ditch the tent. Go back to a real room and give yerself some space. Grow fatness. And tell your neighbors your in a legal state and to go eat many bags full of dicks.

 

[Dr. Who]

Thanks for the invite but, these guys have you covered.

Salt build up, pH, low night temps...That also is helped by high K amounts.

Don't cut ca/Mag in coco though - saw that on the first page....

High N, especially with glossy leaves = reduced THC and trich production too..
High K late = reduced THC concentrations.

Coco in some ways, needs a leeching from time to time - Especially if you don't do any water to run off...

Like I said, the other guys got you covered...I'm repeating..

 

[Flowki]

Quit using the blumats for now, they are adding way to many variables.

You're not the first or last to fail, soldier up snowflake ;p.

Start again as simple as possible, ensure day/night root temps don't go below 60f, fix that for sure. Try a simple nute line, Canna coco A+B is very easy. It requires no use of booster and auto levels ph. You don't need to mess with ratios, you can feed equal amounts start to finish. With a single topping per plant It is able to get 1gpw of light. Unless it's changed over the years.. but highly recommend it to remove variables and see where you are at.

If you want to use blumats introduce it to one plant until you get it dialed in. Pointless risking them all.

Hand watering is best done at around 1L per 30 min/hour until run off daily. Pain in the ass? yes, but you'll have a bigger denser salt free root system that way, evident by more water use. You may need to reduce to half liter per interval if smaller pot of -3gal or so.

 

[RetiredGuerilla]

WTF is this?

Indoor 600w
Coco
RO water
Minimal nutrient system (1 Base, 1 Flower enhancer, CalMag)
Blumat autowatering with 12 gallon reservoir changed weekly.

Looking at growweedeasy.com, looks like a copper deficiency?

Its where the plant is ripening and the night time temps are cool. It does not have a copper def ....LMAO !!! Kush and afghani and other indica dominant strains turn purple when temps get cool and its close to harvest. Pretty isn't she?

 

[Yodaweed]

your container is too small, which makes salt build up much quicker so you got a lockout from salt build up.

 

[Daveindiego]

2 days since the flush.

I’m just going to finish this up using the Blumats, and 1/4 feeding.

They are 3 gal pots in a 5x5 tent.
