Medical Grow – Coco, 1200w. [Himalayan Gold & OG Kush]

[bender420]

yeah, I had a look man, no idea I'm afraid. Could be any number of things. Only on the one plant is it?

I only have experience in coco with canna nutes, followed their exact feeding scheduled for 'normal feeding' and my plants seem to want for nothing. The only addition I made was the top shooter towards the end and I had to add cal-mag throughout as I was using rain water. You're not using canna nutes are you?

My first guess would be P or K deficeincy, or maybe more micro nutrients. It could be lock out from too much buildup of certain nutes. Like I said, I'm just guessing. If it's just one plant, I'd wouldn't worry about it too much.

Did you flush and test run off.... it is the only way to know what is going on in your pots.

You didn't spill any nutes on the plant at all did you that could of got burnt under the light?....that's my only other thought.

Yeah only one plant is doing this. Some of the other ones are starting to show some of the similar rust spots, but it isn't that bad.

I did flush but didn't test the run-off, the water was however very clear, when it came out the bottom.

I will try to keep watering with some run-off so I could wash away the salts and stabilize the pH if need be.

I will feed them pretty low like EC 2.0 for a bit and see how this goes.

I bought a little microscope with a light. It works ok, but you have to touch the bud sometimes damaging it, Im not a big fan, and haven't been able to use it until I cut a bud off. There are some good tutorials on using a hand lense with your digi camera to view trichromes. THe hand lense used is a "slide viewing lense" Along with the digital zoom on your camera. Im looking for the thread. WIll let you know!

I would like to see that thread too!

Just gorgeous Brother!!!

 

[bender420]

Thank you friend.

 

[wonderblunder]

I will find it. It was pretty cool and very simple.

 

[bender420]

Dammit my syringe fell in to roots bottle. I had to stick my finger in to get it. Is the RE gonna be fucked up now or would it easily deal with the bacteria on my skin and the syringe.

 

[wonderblunder]

roots bottle? roots organics. I think it should be fine. I have had similar instances and i never worried about it. Syringes are sweet for measuring nutes......... I love mine. Jerky flavor injector works great too.

 

[bender420]

Holy Crap I test the run-off it was like pH 4.8 and EC 4.7. FUCK FUCK FUCK. I immediately flushed each pot with RO and 5ml/gallon of clearex @ pH 5.5

I know it ain't good to use plain water on COCO. But I am sure even after the flush there will be nutes left in the container.

I will be feeding it white shark to bring the good bacteria back for the last 3 weeks of grow. I guess watering with no run off finally caught up to me.

Those spots on the leaf were definitely burns.

i am so bummed, I don't wanna loose my crop. I hope things bounce back to normal.

I did wonder mate...u were pumping them pretty hard. 3.0 EC was it? I never went higher than 1.8 man.

Good job on testing the run off....you would be none the wiser otherwise and still blindly giving your plants loads of crap, which would of just made things worse. You should of mixed a light dose of nutes though. Just like a seedling strength mix. The bacteria takes time to build, but it's very easy to wash away.

You should flush and and test, flush and test, until your run off is in the expected range. There is no limit to how much water you can flush through a plant at any one time. You can't over water it in one hit.

You are not going to ruin your crop here mate, so don't worry about that. You may of just slowed them down a bit. But don't be dissapointed man. You're still going to pull a shit loads of nice bud from this run.

Thank you Snow for a quick response. You made me feel better and also answered some questions I was gonna ask.

I ran a good bit of water today. They will probably be ready for another flush with a EC 0.8 with great white (bacteria) in 3-4 days. I hope the good bacteria can build up good for the last three weeks.

Man if this slows down that is still bad, but much better than loosing the crop. I hope the quality won't suffer if things are fixed.

 

[bender420]

BTW, what kind of run of am I supposed to be looking for from coco EC? pH?, if they are fed at EC 1.5 pH 5.8

yeah man, you'll be fine. You're doing all the right things.

I would say no higher than 6 PH....5.8 would be perfect and EC, yeah, 1.5/1.6, something like that. Then go nice and easy on them after that. Less is often more.

 

[SnowWhite]

and it's a lot quicker and easier to fix under feeding, compared to over feeding.

Damn man lesson learned, the bitched didn't show any signs of nute burn early on so i thought they could take it.

How long do you recon this would set me back?

So should I do light nutes with the next flush. Or still do clearex and RO.

BTW the botanicare rep told me you should always run clearex by it self with water, never add any nutes to it.

Yeah, I never saw any burn in your tips either. Your levels were very high though, maybe it's all just locked out. IDK.

ah...well I'm not sure about clearex, so I'd listen to them then. Or don't use it and flush with a light feed. 0.8/0.9 EC instead.

I would probably ditch the clearex and flush with a light feed instead myself, but your call man.

Has your PH/EC meter been calibrated recently as well? Just to be sure you're getting good readings.

 

[Don Gin and Ton]

man EC 4.7. FUCK FUCK FUCK. christ im surprised the plants weren't cinders youve had a narrow escaPE THERE BUD

but as snowy rightly says flush with super weak solution and start slowly building back up to 1.6 -1.8 ish

this is a controversial point cos i bust my nutes as high as i can get them and generally have slight tip burn i have no idea the EC but its probably well over 2 for the most part of flowering till flush and i have no probs.

happy growing fella!

 

[wonderblunder]

I need to get a tester. it would help a lot of my questions

12/12 Day 41

The flush w/ clearex see to have gotten a bunch of salts out of the pots. I am very surprised how fast I saw the difference. I compared very closely between today and yesterday, it seems that the leaf burning and spotting on the leaves has completely stopped. I definitely notice more swelling today than I did in the last week.

I also pick up some "White Shark" innoculant, I would greatly appreciate some input on this. Here is a copy paste from the manufacturer. From reading around it seems to be a good product.

Great White is the most advanced mycorrhizal product on the market today. The combination of mycorrhizae, beneficial bacteria, trichoderma, and plant vitamins will give your plants a strong and developed root system. This will enable your plants to break down and absorb nutrients efficiently and effectively. Also it will increase water uptake and the overall absorption area of the root system, resulting in a healthier plant. Can be used in hydroponics as well as soil. May also be injected in to media.

Ingredients:
7 species endo & 11 species ectomycorrhizae
31,200 endo & 1.5 billion ecto propagules per Ib.
19 species bacteria / 2 species Trichoderma /
biostimulant
Vitamin package


Once the pots dry up they will get a light feeding at 1.0 EC, pH 5.8. I will aim for about 20 percent runoff so I can check what is coming out.

Some of the fan leaves are turning purple. It does happen to be the coldest spot in the grow area, so I hope it is from low temps and not anything else.

Brotha thanks for your input, I am going to do exactly as you say.

Dang Don, I don't know how my girls made it through that. I glad things are cooling off now. I got quite scared their for a bit.

LOL, get one ASAP. I got one before I even got my first baby plant.
