hi, ive been looking around for awhile and most of my problems i have solved just by reading but can some one help with this one?
E-indoor
E-pro mix
SCLR-6.4
E- r/o water
E-Source water pH
E-30 days into harvest+2 weeks veg
E- DNF 1 every 2nd watering
E-E-1000 hps
E-Air temperature bout 80
E-Lighting schedule 12/12
Whislt flowering this happened to me, I had a very alkaline PH so I had to balance it, then I discovered I was adding too much nutes and stressing my plants (biobizz allmix), turned out to be a combination of the HID HPS lamps temperature and/or closeness to the plants whilst nuting, which seemed a bit bizarre, this only happened on 12/12 , now I'm using CFL with the same mix and everythings fine.. I'd nute every 2 waterings to see if its that + heat.. if it isnt, i'd then try flushing out.Quote:

hello i just went through that myself (nute burn) like mike said cut way back on ur nute's, i went 1/4 strength and i was fine.. good luck:)
Looking at the surrounding leaves...it doean't look to me like overnute. Is this starting at the bottom and moving-up the plant? Overnute will start showing on virtually all of the leaf-edges, and get worse without correction. Heat stress usually starts at the top, and works it way down.
Possible rootbound...?
To me, it looks more like overwatering or root rot What do the roots look like, and what is your watering schedule? Are you letting the soil dry between waterings?
-or-
Are you spraying or pouring something on the lower leaves?
I agree ... that looks like damage from over-watering, possibly rootbound, and a calcium deficiency ... either stop using reverse-osmosis water, or immediately start adding Cal-Mag+, your plant needs the minerals the RO has stripped from it ... use about 10ml/gallon with the RO, or 5mg with typical water ... good luck :smokin:
i dont think its nute burn, jus cause im useing the dnf at less than half strength, a couple of people i know said it could be air quality, i have just doubled up on half the pots so i will see if mabye it is root bound, i am watering almost every day of every second day but i do wait untill the pots are pretty dry. thanks for the feedback i appreciate it,
it really starts in the middle of the plant, really wierd that some of the very bottom fan leavs are still ok but halfway up da plant it looks terrible
Doesn't look like nuteburn to me either on the largest oldest leaves. I agree with Reaper and Rusty. Add some Cal Mag and check for rootboundness (roots coming out the bottom of your pot).
there is roots coming out of da bottom hole in the centre on most of them, and they are starting to look a little shitty (the bit of roots comming out), could that be it???
Would carefully transplant, and get back to us in a week or two. :thumbsup:
Also, make sure she needs water, before watering her. Cannabis needs to go through a wet/dry cycle. (thanks for the phrasing, IR) Sometimes weather extremes (high humidity, low temps, stronger fans, and on, and on...) can affect rate of soil moisture drop, so watering on a schedule get's screwed-up...and you end-uip watering too often. Personally...I would adjust the ammount of ph'd water you add between nutrient days, to try and keep on a regular schedule.
Why the reverse osmosis water?
im useing the r/o water cause ive had this same problem every time i try a small grow, i thought mabye i wasent checking the ph properly, so i know the r/o water is ph balanced.. thought id give it a try
i do wait (mabye sometimes too long) for the pots to get fairly dry before i water
i did transplant 4 of them yesterday to see if it would make a difference,
again thanks for the help ill take pics now and later of the ones i transplanted cause i know there is alot of different views on this subject (transplanting during flowering)
R/O does nothing noticible to water ph. Period. I found this out when first getting into saltwater reefing. Watch for salesmen with inacurate facts. (nice try, Kinetico and Sears)
Transplanting during early flowering is fine. (within 3 weeks of 12/12, but I rarely go past a week to ten days) Only problems I ever have with it is that my organic soil is hot, and with the extra nitrogen it contains...it makes the ladies stretch for a week or so...but otherwise fine. As far as I'm concerned...with my experience, in my garden...it's not something to get anal about and argue over. If the ladies need more footroom, then give it to them. Or, keep chasing the troubleshooting threads wondering why they always underperform. :jointsmile:
i just ment the r/o water is always the same 6.2 or somewhere in there so i dont have to up it or down it like how i had to when i was useing tap water.. with the transplant i jus figured that even if i stress it for a day of too it should make up for it with 3-4 more weeks of better growing space for the roots
Ok...I'll bite. What's the tap water ph, and where does it come from? The city or your own well...? If the tap ph is witin 6.3 to 6.8, I'd use it. If it smells like chlorine, let it sit overnight.
You've given two ph numbers. 6.4 is borderline low, which is why nobody has mentioned it...but 6.2 is too low. As the peat-based soil ages, it will begin to degrade, and lower the ph even more.
RO water has no real ph.....it takes on the ph of whatever you are adding it to. So it's not REALLY helping your ph issue.....but doesn't add to it.Quote:

It's just not their fault if they don't look at things the way you do. You need to accomidate THEM for a good plant......not really the other way around.
when i was using tap water the ph was high like 7.4 if i remember correctly so i had to bring it down all the time, i have since moved and havent checked the tap water, mabye i will check it phQuote:

jus an update if anyone cares, the plants that got transplanted returned to a nice healthy green and did not keep getting worse.. the few i left did start yellowing and that "rusting" did get worse so you guys were right it was rootbound at least mabye some rot aswell... i have 2 diff types of kush and one took to the transplant very well and the buds look pretty good but the other one did not take to well and dont look as good..either way the problem looks like it has been solved so thanx alot i will let u know how the next one goes with bigger pots.... mabye a little less watering...
i lost my phone with the pics on it but i will try to get some new ones taken if you want to see...
Glad they are doing better! Yes, post a pic so we can see. :)
k these 2 are purple kush that got transplanted (same plant)
this purple kush did not get transplanted
first 2 are kush that got transplanted second 2 are kush that dident
Nice to have a side-by-side comparison. Thanks. Looks like you accidentally got some soil in your perlite, though. :jointsmile:
Considering what they've been through, the transplants are looking good. Nice job. :thumbsup:
thanx.. some of dem do look pretty good considering.... see in a week or so, im not sure if you were joking but im useing straight pro mixQuote:

Perlite floats. Happens often after transplant. :thumbsup:
