coco coir , maxibloom, new growth is lime green / yellow, help?

[smoke_tayo]

hi, been running maxibloom and mag cal in coco watering almost everyday since week 3.

week 5 and 6 after topping, ran the ppm a little high at 1400 when i started noticing the yellowing / lime green leaves. the high ppms didn't seem to correct what i thought was a deficiency so flushed with 500 ppm during first week of flower. they are just starting their 2nd week of flower. my ph has been set at 5.5 each watering.

they were initially under a 600mh. last week put them under two 600hps' at 75%.

i'm having trouble diagnosing what the problem is. i'm thinking either nitrogen deficiency? magnesium? nutrient lock out? or could it be shock from the 2 hps'?

they look healthy, just that i've never seen leaves so light. there is one plant, an auto that i did not top, and the leaves are a nice dark green that i am accustomed to. i've provided a picture of the auto with another plant for reference.

there are about 4 different strains and they all seem to be having the same symptoms of light green growth.

hope someone can shed some light on the matter. thanks!

Just a guess, but at 5.5 pH, some elements are becoming difficult to uptake, like Mg, P, and even N. I'd start by upping pH to 5.8-6.0 and see if you cant catch up a bit with those elements.

Im using maxibloom, and I get yellowing. Im not sold on the stuff.

Definitely, though I personally do like to allow slight ranging on occasion outside both ends of the pH. But I agree, if he's keeping it pegged at such a low pH, that's going to cause some problems. They look pretty good to me, otherwise.

I use Maxibloom and have great growth. Keep the PH either in the 5.8 or 5.2 range. In between those numbers you can have some issues w/ cal/mag deficiencies. Make sure you are using 7 grams per gallon. I always supplement w/ a half strength dose of Calmag+ and Dina Grow Protekt.

 

[JOJO420]

I was using Maxibloom at 3 heaping tablespoons per 4 gallons water, plus Calmag and the plant is flaming yellow. I had to add micro to the mix before I could get my buds back to green. All the fan leaves are yellow, but the bud leaves look good. Outdoor plants can handle some major doses of maxibloom let me tell ya.

jojo420, you're making me lose my faith in maxibloom. lol. there's just so much love for the product, i must be doing something wrong. i always used micro and bloom and never had a problem with light green leaves, would even use grow during veg. nevertheless i'm set on making maxibloom work.

will up the ph for sure, but i have definitely ph'd at 5.8 a couple times. probably right though, only became this stringent with ph since i got a meter. when i had drops i'd let if fall within a color range. perhaps being spot on all the time is to my detriment.

will be ph'ing around 6-6.5 and see if it helps. i hope it isn't some phantom deficiency. i'm so paranoid about these root aphid threads!

i've noticed that 7 grams per gallon brings my ppm's pretty high along with cal mag, i'm hitting 1200-1400 on .5 conversion. maybe i just need to up my ppm with the correct ph and i'll be good. i really hope so.

thanks for chiming in guys! much appreciated!

I tried the K.I.S.S. method both ways and got the same response.

Indoors, my plants did this weird thing where they tried to bud and grow at the same time. Looked like a regrow, but never regrew. Plus the tips were light green/yellow, just like yours. I wasted a bunch of time and a couple really nice clones learning this. I believe it was not enough N and too much P n' K for vigorous veg growth under 400w HPS. All I know is I'm not gonna do that again. It's back to 6/9 with calmag for me, and I'm rippin right along. For my strains, Maxibloom in veg is a no go. Might work for other strains in other rooms, but not mine. Im growing Adubb, ValleyOG, Bluberry Kush and Spicy Thai...

Outside, whole different story. I never even tried using it for veg. Only started using it when the stretch was over. Had a beautiful emerald green plant go yellow within 2 weeks of using Maxibloom at recommended dosages. I found that I had to double it up, plus add up to 5ml per gallon micro to keep the plant from yellowing out. Its a land race Indian Sativa, so not sure why it needs all that micro.It's gotta be that Maxibloom does not have enough nitrogen in 7grams per gallon for outdoor plants in my climate.
The last time I added 3 heaping tablespoons to 4 gallons, no micro and cal mag5ml and the plant looks yellow/green still. The buds seem to be filling in green, while all the fan leaves are dying and turning flaming yellow. I see no burn , no deficiency,just that the plant looks hungry
I believe the plant to be half done, so its not like the yellowing should be happening yet. Only thing I can think of is all the rain. Its been dumping all summer, over 60 inches in the last 3-4 months. Maybe the rain is washing all the nutrients out of my plant??

So yesterday I fed her 8ml micro and 16ml bloom per gallon, ALONG WITH 2 HEAPING TABLESPOONS OF MAXIBLOOM and today she looks better. The yellowing stopped, the buds all look green and the fan leaves look greener. The buds swelled to at least twice their size, no joke. Blew up overnight...
I'm tellin ya, Maxibloom does not have enough N to foster growth at 7 grams a gallon outdoors. That's my experience anyhow and I'm sticking to it.
NO MORE BUYING MAXIBLOOM ...I am gonna finish the bag though, at triple strength

First let me say I have no intention of starting a fight. I just respectfully disagree with this guy.
He is using SUPPLEMENTED maxibloom. He has to use calmag plus proteckt. Again 7 grams per gallon is NOT enough stand alone.
I don't believe he would be getting great growth using just maxibloom. Its the added Nitrogen of the calmag that is keeping him entertained. Otherwise I do believe we would be seeing you in the infirmary forum

 

[smoke_tayo]

what ph do u set your mix at jojo? and what medium are you using?

Dude you're full of shit. 8/16 + 2 TBS maxi would be like 7 EC.
1 TBS maxi/gallon would be almost 500 ppm k alone.
I don't care whether your indoors or out that will kill a plant

 

[JOJO420]

what ph do u set your mix at jojo? and what medium are you using?

Well, depends. In Coco indoors I set my pH to 5.8-6.0 best I can. Never under 5.8 never over 6.3. I use coco and perlite.

If your talking about this plant that Im dumping massive amounts on, well it varies. She is in a mix of coco, perlite and FFOF. She is rootbound to all hell in a 50 gallon woven grow bag.
I mix my mix and get as close to 6 as I can get. I have put as low as 5.6 and as high as 6.7. I put dolomite lime in the mix once or twice, you know put in the powder dolomite and stir it up and pour it on. So mostly I shoot for whatever pH makes it in my range without adding up or down. If I have to add up, I use Protek silicate. I usually have to do that when I use the earthjuice and guano as it makes my pH go to low 4, high 3's.. Even though our troll Ziggaro does not believe me, I have put the 8/16 plus the maxibloom plus the protek all in 4 gallons multiple times and fed this plant. Tell someone on ICmag that they cant do something, or they are lying and watch your ass get proven wrong,lol.. Its a weed remember, espescially outdoors.

Maxibloom has got to be the easiest shit on the planet.

When i started coco i went with the maxibloom.......easy peasy.


JOJO i see you mentioned havin dol lime in the mix.I have always wondered how that works.Dolo will keep the ph up right around 7.0......but the preferred ph in coco is any where from 5.5-6.0 with the majority of peeps.What is the lime for?

 

[JOJO420]

No dolomite in coco, never. it was for my monster outdoor plant.

 

[smoke_tayo]

after having flushed and readjusted my ph, i'm in agreement with jojo420 on maxibloom's effectiveness.

maxibloom may work for some strains, but if you have a hungry one who needs nitrogen straight maxibloom ain't going to cut it. last two feedings i've been putting 10 grams per gal and although the yellowing has lessened on some, the problem is still present. i do not want to have to add 14 grams per gal just to correct an N deficiency and risk burning my plants because of too much p and k.

i believe maxigro could help remedy the situation. even when i used the lucas with gh micro and bloom i'd occasionally mix up some grow during veg and always noticed more lush growth.

sure you can get by with maxibloom and for certain strains it seems to be more than adequate, but i think i'm going back to gh 3-part after i finish all this pink powder.

Why do you refer to this person as "this guy" when he is right here and a part of this discussion?

I have always been a promix/moo doo/ and the 2 maxi products. In my personal experience if I have not added enough lime, then the yellowing occurs that looks much the same as mine do when they are deficient in calcium and mag.

Your mileage may vary.
