nute burn, cutting affected leaves

[Smoken-n-Token]

I figured I'll chime in . You may take this with a grain of salt as I never grown in Coco or soil.

But when I run into these problems in aeroponics I have a saying "when in doubt dump it out" I'll flush the plant with 5.7 PH water for 24 to 48 hours and then start with a balanced nutrition plan 20-20-20 with a low TDS. Work that TDS up and then switch to my standard NUT plan . As it was a surefire way for me because I'm not too familiar with identifying problems beyond the obvious . That's my way of keeping things simple

But of course, if the plants start to get better and I switch back to my standard plan and they start to get worse again, then i know my plan is wrong. I know it can be argued that my initial plan was wrong due to the fact that the plant had problems. But also can be argued that a simple mistake was made that could cause a whole string of cascading problems in the plant. Don't want to be chasing my tail so "when in doubt dump it out"

Yeah I figured i'll argue with myself to save time in other post. lol

But again, I'm not sure how that would apply to your situation as it's not a simple thing as switching out of reservoir but maybe the idea can be adapted to your situation possibly?

Apology accepted.

N sources - ammonium sulfate, ammonium nitrate, UAN (ammonium nitrate+urea in liquid form), blood meal, 30-10-10 or other high N foods like fish emulsion - 5-1-1, urea.

Just because you add more food doesn't mean you're correcting the problem....you're also adding more of everything else too. Remember that nutrient antagonism thingie I was referring you too? You really need to become familiar with that concept. Check out this link and just for grins look at what an excess of P does regarding antagonism of other elements like micros which I pointed out earlier during our shitfest. http://www.ces.ncsu.edu/depts/hort/consumer/quickref/fertilizer/nutri_def.html This all may create an "oh my gawd" rather confusing, anxiety provoking reaction. Don't go overboard on any one element in a food which means don't believe the vendor hype. Trust me, they are NOT on your side. They're selling you what they think you want to buy into. If your foods are fairly well balanced, you'll do fine.

Again, I raise incredible pot from start to finish in a 3 gal. pot of custom made soil and a 12 month slow release 18-4-9 encapsulated food, see the label. Contrary to the misguided albeit "popular" forum paradigm, this high N and low P works great as witnessed in 7' high O. Haze plants I've shown. Cannabis is a tropical foliage plant that flowers. It needs plenty of N.

AGAIN, learn plant nutrition which means empower yourself with knowledge so some cash sucking cannabis shyster doesn't screw you. Get rid of what you have since you don't know what the nutritional values are and then buy a "normal" food like JR Peters or Dyna-Gro, not cannabis specific. They can be trusted not to sell you a bunch of crap, the salts used are of very high quality, and they are one part, value oriented products.

Good luck

Thanks for the reply, the plant nutrition part is quiet daunting when you don't know anything about it, i found out im already using some kind of fish oil, im gonna flush my plants and switch the bloom food for something different, im gonna keep the vitamans and fish oils, because ive been told its doubtful there causing harm its more than likely that the veg and bloom were extremly weak in the nutrients that the plant needed especially for a coco soil grow, which again i dont know if its true but it sounds logical, from this day im gonna research plant nutrition as i think like you said its the most important of growing good bud, i wanna learn to do that, ill keep you updated on what i do next, cheers

Any reply is welcome as its all experiences from fellow growers, appreciate the reply mate

You said that you flip the lights correct? Correct me if I'm wrong but during the flowering stage there's not too much you can do to fix the plant . This is because the plant is entering its final stages of life, and at this point it's no longer going to try to repair itself and grow, it just wants to produce THC and buds. So in a way it's going into its death rolls. The plant is literally going to kill itself to produce THC in buds.



My suggestion and what I would do:
I agree, I definitely would flush for a few days then give the plant what it needs for blooming. Like I said before the plant is not interested and its own health at this point. Just once to produce THC and buds. Which is quite beautiful in a way, self sacrificing.

Cant belive mi plants are gonna die, gutted lol

 

[ItsJustMe84]

Since i clipped the dead leafs and up'd my feed my leafs have started turning much darker, u think there on the mend guys? They dont look half as light as they did

 

[ItsJustMe84]

Maybe the veg feed i was giving them was no good cause since i switched to flower feed they seem to be so much greener

 

[Dboi87]

Your plants aren't going to die. Yield will be hurt but if you balance out the feeding they'll be fine

 

[Dboi87]

Btw when you "flush" , or leach the soil in botanical terms, just run tap water through your medium at 2x the amount of soil. So say your in a two gallon pot, slowly run 4 gallons through it. That should get rid of any salt (nutrient) buildup. After that wait a half hour or so and give it a light feeding of balanced fertilizer until you see a bit of run off. Not sure where people get this 24 to 48 hr stuff from. That's just depriving them of what they need. Then just wait until they need another watering/feed.

Yes well i flushed then and resumed with my normal feed at a higher dose, since then they seem to be doing alot better

Makes one wonder.

Makes one wonder.

....Indeed it does~~~

 

[ItsJustMe84]

Well it seems like my plants have more a less fully recovered, thankgod i come on this post when i did, even though i disagreed and argued with most of you're opinions, i appreciate the feedback as it might of just saved mi plants

Did you ever figure out what you're giving them?

 

[ItsJustMe84]

I know what the npk on the veg feed is 5.1/7.8/2.6, ill find the flower now

 

[ItsJustMe84]

My flowerings 5/9.6/4.6, both are meant specifically for coco mediums

 

[Uncle Ben]

My flowerings 5/9.6/4.6, both are meant specifically for coco mediums

Veg - 5-8-3
Flower - 5-10-5 which might be OK if there's chelated micros.

Plants don't need that much P. As I tried to show you that ratio can create a lockout of micros. A normal, good ratio for veg would always be higher in N, like a 3-1-2 ratio. Bloom (which you really don't need) is usually a 1-3-2.

 

[ItsJustMe84]

Yes im just trying to get a grip on what it all means, next time i'm definatly gonna makesure im more prepared with my nutrient plan, ive also got some kind of fish oils and vitamans, will i be ok carrying on with what ive got for this grow?

 

[Uncle Ben]

Yes im just trying to get a grip on what it all means,

Meaning you read and understand my links on plant nutrition and ordered Mel Frank's book plus a high P food is not good in the long run?

I still don't believe I'm getting thru, that, or you are reluctant for change.

Sure as hell aint gonna learn anything lurking here where the blind are following the blind.

Plants don't need vitamins, they make their own. Wean yourself off the snake oil vendor's teat.

You can use whatever you want, stay with it but coco has no nutritional value for a while so you need a complete food that has all 13 essential elements. Go back and read the last couple of pages. There's some real gems there. Dboi has some great advice.
