Organic PBP Deficiency???

[UNREGISTRD]

sup everyone long time no post huh!!
Well going through alot of shit lately and and have managed to get a couple plants back up and going thanks to some good friends!!
I decided to go Organic for this run just for the hell of it to see whats all about and so far so good but this nute change i saw some serius problems!!
Ive noticed a couple weeks ago just on 3 leaves but figured it was just a bit overdue for some fresh nutes and here I am in the same position with the same problem and more leaves are sick!!! IM not sure if its Nitrogen or Magneseum???
Im running PureBlendPro Bloom 2.5 at full strength have been there whole life and know all the sudden problems..I use hydroplex as the supplement so im not sure whats wrong if someone in organics could help id appreciate it!!!
Im so tempted to throw like 4oz of some floramicro in the res to bump up the nitro levels but am wondering if that will contaminant the whole organic theory,lol...Im so lost with this organics I can pretty much say ill be sticking to my original lucas formula Gh nutes for the future!!
Attatched are some pics of whats going on from left to right u can see how they slowly go to there DEATH!!

I use pbp and have never gone over 15 ml per Gal.What is your PH/ec/ppm And canopy Temp?

I use pbp and have never gone over 12 ml per Gal. With 3mil Liquid Karma. What is your PH/ec/ppm And canopy Temp?

Wow...Ive been under the impression to run it as stated I couldve sworn i read that here!!
Im running PBP at 30ml with 5ml of hydroplex...ITs done GREAT up till know which is the 5th week!! Ive got 3 weeks left and need to get it under control.
Are u changing nutes every week??? Im doing it every 2 weeks in a 40gal and topping off with water at the week interval! It measure 1330ppm and 5.95ph at the week interval after topping off so I dunno u think im overfeeding?? My temps are constant 77-82 day and 65 at night!!

 

[BadKarma]

I change my nutes at 50% addback, and because I have a small rez it comes out to about 10 days. My ppm never go over 1000 with the strain im growing now which is Jack Herer. The ppm seems a bit high. Your PH and temps look good. . Are you using RO water with calmag? And are you using Rockwool as a medium?

I like to do a short flush at about 30 days just to get the buildup out of my rockwool.

AFTER RE-READING many post I see several growers using PBP at well over 1000 ppm. With great success.

Rates on the bottle are much too strong. Where on the plant are the leaves burning? Top or bottom? PBP needs more calcium and magnesium to be complete. You could add calcium chloride, powdered gypsum, or calcium nitrate to get more calcium. You could add epsom salts to get more magnesium easily. Cal mag plus is a store bought suppliment.

I get that too sometimes with PBP. I add 1/8 gypsum (calcium) and 1/8 epsom (magnesium) per gallon. or just buy Cal mag+ like guy above said, but it has nitrogen.
Hydroplex doesn't dose calcium if I remember correctly. Anytime U raise P&K U should probably also raise Ca & Mg in appropriate proportions....or least I have to with the tap water I use. Good Luck.

I've been giving my plants 15ml PBP and 15ml Liquid Karma, and they're looking great. LK isn't really a nute, just helps out with stuff, so 15ml PBP is working for me. I'm sure you could use less than you are now without suffering any negative effects.

Within 3 days of posting this the yellowing/burning has Gone all to the top know!! OMG IM so upset! Ive tried using cal-mag before and it did nothing but fry my plants cuase we have such Hardwater here!! I did some readings just after topping it off the other day and just within 3 days the ppm rose to 1600 and the Ec was 3538!!! and the PH was 4.98!!! Like what is going on???

Either way I wasnt happy with that so I immeditatly drained teh res and am flushing with Floraklleen for a couple hours maybe a day im thinking I checked the flush water and its 240ppm 580ec 6.10ph so Im almost thinking some Organic crap died in my res and made it toxic?????? Cause the flush water seems right on to me where as the other reading was out of this world

This statement is completly correct and is more less the reason i ran the nutes themselves at full strength cause I love to hit em hard with the booster but in this case i still think they may need MORE!! Im looking at the symptoms of my sickness and Im really thinking its starting as a n problem cause reading the statistics of N the corners of the leaves burn and curl up and yellow between the viens then burn up completly and thats exactly what i got going on the ends are starting to fry and are stickin straight up!! I guess maybe I need to back off the booster i dunno Im really thinking of refilling the res with my normal reg of GH nutes!

 

[UNREGISTRD]

well ive started flushing with Florakleen and as mentioned above its ran twice at 30min intervals and i just took some water out of the rockwool with a syringe and tested that water and OMG! its got 600ppm and over 1300ec with the same 6.10Ph so Im almost positive my rockwool is contaminated or something!!! HOW do i flush out the rw cubes completely so they test the same as teh water???

I had that same deficiency a couple times when I was using PBPBS and Cal/mag+ in pro-mix.

I couldn't figure it out exactly, but I was able to clear it up both times. Only problem is I'm not sure what did it. I flushed em and foliared with PBPB and cal/mag on seperate occasions.

I think it's a phosphorous deficiency. I could be wrong though.

 

[meduser180056]

It starts on the tips usually right? and then starts curling up and browning back towards the stem of the leaf? Happens on upper leaves, middle leaves. Really seems to stunt growth.

Those pics look exactly like mine did. I hated it.

How often??

How often??

I've been giving my plants 15ml PBP and 15ml Liquid Karma, and they're looking great. LK isn't really a nute, just helps out with stuff, so 15ml PBP is working for me. I'm sure you could use less than you are now without suffering any negative effects.

Hello! I am pretty new to this. I just picked up some Pure Blend Pro Soil Bloom Formula and some Liquid Karma and Thrive Alive. I was thinking of doing 15ml of PBP, 10ml of LK, and 5ml of TA. But how often should I feed them? The PBP says to feed with every watering, but this seems excessive. Would every second or third watering be sufficient? I use FoxFarm Ocean Forest brand potting soil. Thanks for any advice.

 

[bounty29]

I'm not too sure what Thrive Alive is or how to dose it, but I think 15ml of PBP and 10ml of LK would work great. I've fed with every watering before, and saw no signs of problems, just great growth. Right now though, I've been watering with full dosage twice, and then with just PH corrected water the third time. That seems to be working pretty good. I'm using a FFOF and perlite mix, probably about 60/40. Check out my thread if you have any more questions though, I think PBP can be used in a very simple feeding program and get great results.

What pH level do you adjust to in soil? I've been reading around here and I've seen everything from 5.8-6.8 to "pH doesn't matter in soil." I don't know what to believe.

I myself NEVER do a run without Cal-Mag and I also threw away rock-wool years ago and went to Rapid Rooters. If the rock is your thing more power to ya but I feel you will see they are sometimes more trouble than they are worth and makes ya understand glass is to smoke out of. Got any more pics?

Mr.Wags

ya the rock is my thing i guess! its easy to use and get rid of and no mess!!
Ill get some more pics up in a minute or so ull see why im depressed!
Ive been flushing only half way up the cube so i need to get the water level higher to flush the whole cube and test the rw's water then and hopefully it will have flushed itself by then!

 

[UNREGISTRD]

Ok everyone here is some more detailed pics of whats happening!

first one is the leaf of how is starting and the next is the result a week later!!

 

[imnotcrazy]

I know you mentioned you are mixing into a Rez, but you didn't say what kind of system you are running. I had the same issues when I first switched to PBP/LK in my Ebb & Flow Systems. On MrWags and King Ralph's advice, I backed down on my nute strength and the problem sorted itself. Full strength looks OK on a PPM/EC meter but is WAYYYYY TOO STRONG IMHO

 

[gratefuldawg]

Looks like calcium defieciency to me. Add 5ml calmag plus per gallon, lower PBP to 15ml per gallon. Flush first.
