First time grow ever in coco and some problems. Please look.

[wegonnasee]

What's up everyone.

It's my firt time grow and I'm using COCO as my medium. I will do pictures and document my grow room when I have the time to do so.

Now I just wanna ask you if you could look at some pics of leaves cuz there is something wrong with them I think I've overfeed them a little but I'd like some other opinions.

Some basic info:
Medium: Plagron coco mixed with perlit
Lamp: 600W HPS
Temp: 24-29 °C (75-85 F)
Humidity: 50-60%
Pots: 6.5L
Fertilizer: Advanced Hydroponics (grow, bloom, micro) + AH Enzymes (I had these so I'm using them, next time I'm gonna go with CANNA coco specific Fertilizers)

Water: PH ~5.8; EC ~0.8;
Run-off: PH ~6.2; EC same as go in ~0.8;

I didnt have EC & PH Meter and I had EC around 1.1-1.2 so I flushed them and adjusted EC to 0.8;

Well look at those pictures and please let me know what do ya think, I've diagnosed it as overfeeding but I could be very wrong .

Any help will be very appreciated.

btw: Sorry for my English, it's not my native language

Thats really no big deal I think.........I'm guessing those are lower older fan leaves

 

[wegonnasee]

So I should not worry about it much?

What do you mean by "fan leaves"?

Otherwise plants look healthy I think, this is the only thing that worries me a little.

Thanks.

How's the new growth? Looks like evidence of a little stress/overfeed on older fans probably from when the cut was young....

 

[wegonnasee]

They are one week and half under HPS in vegetation.

And yeah I've stressed them when they were young, I had light too close and I've overwatered them a little.

I've corrected the light and start paying close attention to watering and they started growing and new leaves were nice and green. But after few days those big nice, green leaves got brown/yeallow edges.

As I said I didnt have EC meter and when I got one I've measured my nutes solution and EC was 1.1-1.2 (so was run-off). I thought it was too much so last 3 days (maybe 4) my solution has EC 0.8 and I think that they are getting better but I'm not sure.

It's my first time grow indoor so I'm sure I'm making mistakes, but hopefully I'll learn from them

Agree, check the new growth and check your pH. Get a simple tester kit with the drops. about 10 bucks US.

I don't use perlite but don't think you can over water coco. Are you draining and throwing away the waste?

 

[wegonnasee]

I already got digital Ph & EC meters I didn't have them at the begining...

ph is 5.8 and ec 0.8;

And yeah I water to run-off(about 15-30%) and then throw away the waste. Overwatering my clones was mine mistake but now I handle the run-off and I could not overwater it even if I wanted to I think ...

The perlit in coco should just hold more Air for the roots and cause the coco drain i little faster.

So now I should just check the new growth?

Thanks.

Leaves don't recover, your new growth is all you can assess.

I think you're a little acidic but not by much.

This may be another case of worrying too much

 

[wegonnasee]

mr.mustard: well I just wanted to ask you know I don't have many experience so better be safe then sorry. But propably yeah I worry too much.

Well what PH do you think I should have? I've read that I should treat coco like hydro and my PH should be 5.8-6.0 so I aim at 5.8.

 

[mean mr.mustard]

It's fine.

Be happy, don't worry.



I have mine at low 6's and like it like that.

I don't think it makes that much of a difference.

 

[wegonnasee]

Just don't wanna make too many mistakes.

I will document my room in 2 or so days, will appreciate any input and critique.

Thanks for now guys

I have something very similar happen to me now and again, but it seems like a flush with FloraKleen does the trick.

When they are that small, it's easy to overwater. People seem to say that you can't overwater coco but I believe that is hogwash. Until the plant can soak up all the moisture within 1.5-2 days then they do not need to be watered much. Overwatering + some salt buildup is what my guess is with yours.

Again, I would recommend FloraKleen from General Hydro to use a few times throughout the entire grow.

I usually feed,feed,feed,feed, flush (repeat).

Also, don't worry too much about it at the moment, they don't look terrible, and in another week or two they should really take off.

OTP: Mmm FloraKleen looks pretty good. I did flush it pretty well with ph adjusted water, but I'll propably find e-shop that is sending to EU and get FloraKleen coz my local growshop doesn't have it and e-shops in my country doesn't seem to have it as well. I did not hear about this product and I think it could be very good for flushing. Btw if you have experience with this product, can you use it for flush on end of flowering? Does it affect smell & taste? Or do you flush just with plain water?

I don't think I have any salt build up as I measure EC of my solution as well as I measure EC of run-off and they are the same or run-off EC is little bit lower. If I had salt build up wouldn't be EC of run-off bigger then EC of my solution?

 

[resinryder]

I'l be honest with you about EC. When I transplant cuts into their pots I feed with an EC of 1.0 the first week. Week 2 I move up to EC 1.2, Week 3 if things are looking good and they usually do, I move up to 1.4. Week 4 on until the final days of bloom when I start flushing I keep the EC between 1.4 to 1.6. Very rarely do I go any higher unless the strain is looking like it needs more. I do run coco in E&F.
I keep the PH around 5.8 to 6.1 in veg and 6.0 to 6.2 in bloom.
I also don't see where you are using a cal mag type of product. Coco needs it added and so will your plants. Start them off around 2ml/gallon in veg and 4 to 5 in bloom. Again that is strain specific based on the plants needs.
If you were at 1.2 in veg during the first week that may have been the problem. That's why I start at EC 1.0.
Also, did you wash the coco well before use. Many of the brands of coco have a lot of salt in it that will cause what you are seeing there. Some brands higher than others. The salts will show as a high EC reading too. Measure the EC of the water you normally use. then take some of the coco, put in your water and stick your EC meter in it to see what you have. The difference will be the salt content in the coco. You may need to wash the coco several times to rinse the salt buildup out of it.

OTP: I'm looking at this http://mariamarkt.com/final-solution-advanced-hydroponics-holland-p-965.html?language=en it should be very similiar as FloraKleen and I can get it in my local growshop.

resinryder: Yeah, I figured after lot of reading that my EC was high. But I didnt have EC meter so I didnt know what my EC was. The day I got EC meter I flushed pretty well so now I have EC 0.8 and will be slowly adding.

For the cal mag - what would you reccomend? I really don't know what product to look for? I have something that has Mg, Fe, Mn, Cu, Zn, Mo but I don't use it coz I'm not sure what it is
edit: Do you mean somethink like this? http://www.head-nature.com/04788.html and http://www.plantasia.co.uk/index.ph...ion=com_virtuemart&Itemid=4&vmcchk=1&Itemid=4


I didn't wash the coco as I didn't know that I'm supposed to do so. But if my coco had high salt level wouldnt be my run-off water EC much higher then EC of my solution?

 

[OPT]

If you didn't wash the coco, that may be your problem, but again, they don't look bad, so don't worry yourself too much!

As far as that product goes, I guess it sounds similar to the FloraKleen. Mine too says to use it as a final flush, but I use it periodically through the whole process. Don't think you have to get it right away or your plants will die or something, it may be something that would just be good to have around.

But, from what I'm hearing about Advanced Nutrients brand, there shit is pretty top notch. It just doesn't sound right that you would be lacking cal or mag using those products. The only reason I say this is because since I've starting using coco, I've used the plain ole Flora Series from GeneralHydroponics, and I've never had a problem in the cal/mag department.

With how much more "high tech" advanced nutrients seem to me, It's just hard for me to think that would be the case.

I guess I don't know how much stuff your tap water has in it, but in my parts of the world we have plenty of calcium in the water here, enough to satisfy the plants need for it. But, this actually causes salts to get built up in my medium faster then most, this is why I use this FloraKleen about once every 1.5-2 weeks, to pull them salts out.

Let them go and see how the new growth responds over the next week or two, and judge if the problem is still there or not.

Also, kind of silly question, but you are mixing the nutrients seperate first right? With these types of nutes you need to put the micro in, mix, put the next in , mix, etc.

magnesium deficiency, maybe...

 

[blueberrydrumz]

can u pls re-up ure pics... thx

 

[IwannatokeNbone]

my adivce n i realize its very fashion forward would be to feed your plant n not the dam coco, but what do i know, i ran coco with tap, no ec meter or ph meter n never had a problem, coco is no differant then peat or soil when fed chems, just dries out quicker, dont make more of it then need be, get a nute with cal/mag n call it a day.
